Excel Custom Renderer To Remove Hyperlinks

Nov 20, 2007

Hi,
We are having a problem with the Excel renderer that comes with RS2005, It doesn't have an option to OmitHyperlinks so when we export files they come out over 20x the size they should be. So what I'm trying to do is write a Custom Renderer that will take in the Report Object, and Strip out the hyperlinks, then pass it on to the RS ExcelRenderer, but I ran into a little problem.

I'm looping through the ReportItems, and trying to clear out all the Hyperlinks but I keep getting this exception:

Operation is not valid due to the current state of the object.

This is the part of the code thats throwing up the exception.



Code Block
Action action = txtBox.ActionInfo.Actions[a];
action.SetHyperlinkAction(String.Empty, null);


Does any one have any insight on how to solve something like this ? Or even another way exporting an excel file with out any hyperlinks ?

Thanks

-Raul

Custom Report Renderer Throwing An Exception

Jan 31, 2008

I have to create a custom rendering extension for SQL Server 2005 Reporting Services.

I followed the instructions in the MSDN article: http://msdn.microsoft.com/msdnmag/issues/05/02/CustomRenderers/default.aspx

I am running the report server under an administrative account provileges on the local machine (XP Pro SP2).
The Reporting Services is installed for SQL Server 2005 Trial/Evaluation Edition (not expired yet) and has been upgraded to Service Pack 2.
The Report Manager runs under a default ASPNET account.

After deploying the extension according to instructions in the article, I see the custom renderer in the list of available rendering formats in the dropdown in the Report Manager.

However, when I select that renderer and click "Export", a new IE window opens with the following error message:


Server Error in '/Reports$SQLSERVER2005DEV' Application.


That assembly does not allow partially trusted callers.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Exception: That assembly does not allow partially trusted callers.

Version Information: Microsoft .NET Framework Version:2.0.50727.1433; ASP.NET Version:2.0.50727.1433


My "why is it not working" question basically breaks down to 3 questions:

1. Why does this error say "partially trusted" whereas the new element in the rssrvpolicy.config file explicitly asks for "FullTrust" permissions?

2. Is there any deployment step that I'm missing?
[For now, it's:
- copy-and-paste the dll into ReportServerin directory;
- add a new CodeGroup element to the rssrvpolicy.config file;
- add a new Extension element to the rsreportserver.config file;
- IIS reset;
- Reporting Services service restart.]

3. Also, I checked the deployment instructions in BOL (Deploying Rendering Extension: http://msdn2.microsoft.com/en-us/library/ms154516.aspx), just to make sure I didn't miss anything.
An interesting this is, the BOL article does NOT mention a requirement for adding a new element into rssrvpolicy.config file.
Is this an error in the September 2007 Books Online?


The same error (regarding "partically trusted" - see above) occurs even after I signed the assembly with a strong name key (although this is not mentioned in the articles, but I figured it might be necessary).

Could someone point me in the right direction as to how to properly deploy a custom rendering extension, please?

Thanks a lot!

Custom Renderer In SharePoint Integrated Mode

Jun 27, 2007

We have been successful in creating a custom Excel Renderer that works very well on a server configured for SSRS Native mode. However we have another server that is configured to work in SSRS integrated mode that we can not get this custom renderer to work properly. The steps we follow are:

After the report results are displayed we select Actions -> Export -> Excel Custom . So I can see the name of our custom rendering type.
After a very short amount of time (no more than a second or 2) I get a frame that says: an unexpected error has occurred. Here is the URL of the web site:

http://sharepointserver/sites/BI/Reports/Reserved.ReportViewerWebPart.axd?ReportSession=2jqe4e45sm0sze553avovv55&ControlID=5c4fbb59def64efdac050393cd3fb338&Culture=1033&UICulture=1033&ReportStack=1&OpType=Export&FileName=edi001&ContentDisposition=OnlyHtmlInline&Format=CUSTOM_RENDERER



Is there anything that has to be done differently to get a custom renderer to work in SharePoint integrated mode?



Note: here is the article we followed to initially create the renderer that will work in SSRS native mode:
http://msdn.microsoft.com/msdnmag/issues/05/02/CustomRenderers/



Any help would be appreciated, thanks.

Problem Deploying A Custom Renderer On MSRS 2005.

Mar 4, 2007

Hi,


I have been struggling to deploy a custom rendering extension onto
Reporting services 2005. I have followed all the steps given in the
MSDN article
http://msdn.microsoft.com/msdnmag/issues/05/02/customrenderers/defaul...


Especially -


1. Copied the dll generated to the reporting service bin folder.


2. Made the entry in C:Program FilesMicrosoft SQL ServerMSSQL.
3Reporting ServicesReportServer
sreportserver.config file as
<Extension Name="CUSTOM_RENDERER"
Type="MSDNMagazine.CustomRSRenderer.Renderer,MSDNMagazine.CustomRSRenderer"­/




3. Made an entry in C:Program FilesMicrosoft SQL ServerMSSQL.
3Reporting ServicesReportServer
ssrvpolicy.config file as


<CodeGroup class="UnionCodeGroup" version="1"

Description="This code group grants data extensions full trust.">
<IMembershipCondition class="UrlMembershipCondition" version="1"
Url="C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting Services

</CodeGroup>


I am able to see the extension being listed in the Report manager list
of available rendering options,
But I get the following error from the report server when I try
exporting to the custom rendering extension




An attempt has been made to use a rendering extension that is not
registered for this report server.

Custom Property For Remove Duplicates Transform Input Row

Oct 15, 2006

Im working through the MS example of "removeDuplicates". I cant seem to figure out how to add custom property for input column.

I added the helper method:
private static void AddIsKeyCustomPropertyToInput(IDTSInput90 input, object value)
{
IDTSCustomProperty90 isKey = input.CustomPropertyCollection.New();
isKey.Name = "IsKey";
isKey.Value = value;
}
I call it from:
public override void ProvideComponentProperties()
{
//...
AddIsKeyCustomPropertyToInput(input, false);
//...
}
public override void ReinitializeMetaData()
{
IDTSInput90 input = ComponentMetaData.InputCollection[0];
if (input.CustomPropertyCollection.Count == 0)
{
AddIsKeyCustomPropertyToInput(input, false);
}
// ...
}

However when I deployed it and added the component to SSIS package - I cant see the Custom Column "IsKey" in the input column properties window.
What am I missing - please help

Remove A Row In Excel

Feb 26, 2008

Hi gurus,

I got a pre-formated excel sheet as destination. The header is formatted with color.

The requirement is to populate the excel sheet with different data type (name(string), no (int), sal(int), age(int)) from second row onwards. The source data is a SQL table and I am using SSIS to export data to the above excel destination.

Problem:
Scenario 1: Using SSIS data flow, populate the excel sheet. In this case, the format of the first row is used by all the new inserted records. So, I am not able to format as per the data type requirement.

Scenario 2: To populate data with required data types, I need to format the second row with the specified data types and then export data into the excel in the SSIS data flow. In this case, there is a blank row in the second row position as shown in the picture:
(see the picture on url)
http://picasaweb.google.co.uk/h.zulfi/SsisExcel/photo#5171040908106882370

To meet the requirement, I need to remove the blank row in the excel destination. It should look like below:
http://picasaweb.google.co.uk/h.zulfi/SsisExcel/photo#5171040912401849682
Is there any other method to achieve the export of data meeting the specified requirement?

If no, then is there any method to remove the blank row from excel apart from using com objects to remove the blank row and shift cells up right.

Any thought and help in this regard would be much appreciated.

Cheers,
Zulfi

Export To Excel Custom Format

Feb 23, 2007

Hi,

I have a problem when exporting a report to Excel.

The problem is with the custom formatting. The report has a field named amount with its format property = C (on the properties window of the textbox in the report designer). When the user exports the report everything seems ok, calculations and so on... but the problem is when from another workbook a cell makes a reference to the cell amount of the exported report. The exported report, has this format [$-1010409]$#,##0.00;($#,##0.00) on the amount cell. In fact every format type of the report designer, begins with [$-1010409].

To reproduce this error:

Make a simple rdl with a textbox format C. Export it to excel. Create a new workbook and make a cell reference to the exported report formated textbox cell (='\ComputerFolder[ExportedReport.xls]Sheet1'!$E$15). Close the exported report and the new workbook, open the new workbook (not the exported one) and update the reference. Results in a #Ref error.

Tnx of your time and effort.

Sorry for my bad english.

Maintaining Custom Colors When Exporting To Excel

May 28, 2007

I am using RGB HEX #s in my report for some colors. It shows up fine when rendering to a browser, however when exporting to Excel my custom colors don't come over. I've tried creating a report.xlt file with my custom colors in it, but when I export to Excel it uses the standard Excel palette instead of the custom palette in my report.xlt.



Any ideas on how to retain my custom colors when exporting to Excel?

Reporting Services, Hyperlinks And Frames

Feb 4, 2008

Hello, Im running into some frustrations with the Jump to Hyperlink feature in SSRS. I have a report containing hyperlinks to a URL. Just to keep it simple for now, Ive made that URL http://www.google.com.

Below is the javascript Im using as my expression value to create the hyperlink on the report:


="javascript:void(window.open('http://www.google.com/', 'popup','location=no,toolbar=no,resizable=1'))"

The hyperlink works fine when its parent report is not loaded into a frame; a new browser window opens and loads up Google as expected. But as soon as the parent report is loaded into a frame, the hyperlink doesnt respond at all. I click, and the page just sits there, no error message, nothing. Ive combed quite a few posts and cant come up with any thing that works other than to remove the parent report from the frame and load it into its own browser window. Unfortunately I have to make this work in a frame, because the entire website hinges on this design.

Any ideas as to why the report hyperlinks just seem to go dead when called from a report that resides inside a frame?

Thanks much

Recently we upgraded to SSRS-2008 R2 from SSRS-2008 (enterprise edition) and noticed that all the underlines for hyper-links in all reports are missing. Also the font color has reset back to default color (had set to blue to indicate a hyperlink).

Redeployed the same report from VS-2008 SP1 but no luck. Although the formatting (color + underline) looks ok in the preview mode in VS.if there's any workarounds as many end users are getting confued with this change.

Displaying Custom Properties For Custom Transformation In Custom UI

Mar 8, 2007

Hi,

I am creating a custom transformation component, and a custom user interface for that component.

In
my custom UI, I want to show the custom properties, and allow users to
edit these properties similar to how the advanced editor shows the
properties.

I know in my UI I need to create a "Property Grid".
In
the properties of this grid, I can select the object I want to display
data for, however, the only objects that appear are the objects that I
have already created within this UI, and not the actual component
object with the custom properties.

How do I go about getting the properties for my transformation component listed in this property grid?

I am writing in C#.

Expression Editor On Custom Properties On Custom Data Flow Component

Aug 14, 2007

Hi,

I've created a Custom Data Flow Component and added some Custom Properties.

I want the user to set the contents using an expression. I did some research and come up with the folowing:





Code Snippet
IDTSCustomProperty90 SourceTableProperty = ComponentMetaData.CustomPropertyCollection.New();
SourceTableProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
SourceTableProperty.Name = "SourceTable";






But it doesn't work, if I enter @[System:ackageName] in the field. It comes out "@[System:ackageName]" instead of the actual package name.

I'm also unable to find how I can tell the designer to show the Expression editor. I would like to see the elipses (...) next to my field.

Any help would be greatly appreciated!

Thank you

Expression Issue With Custom Data Flow Component And Custom Property

Apr 2, 2007

Hi,



I'm trying to enable Expression for a custom property in my custom data flow component.

Here is the code I wrote to declare the custom property:



public override void ProvideComponentProperties()

{


ComponentMetaData.RuntimeConnectionCollection.RemoveAll();

RemoveAllInputsOutputsAndCustomProperties();



IDTSCustomProperty90 prop = ComponentMetaData.CustomPropertyCollection.New();

prop.Name = "MyProperty";

prop.Description = "My property description";

prop.Value = string.Empty;

prop.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;



...

}



In design mode, I can assign an expression to my custom property, but it get evaluated in design mode and not in runtime

Here is my expression (a file name based on a date contained in a user variable):



"DB" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + "\" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + ".VER"



@[User::varCurrentDate] is a DateTime variable and is assign to 0 at design time

So the expression is evaluated as: "DB189912189912.VER".



My package contains 2 data flow.

At runtime,

The first one is responsible to set a valid date in @[User::varCurrentDate] variable. (the date is 2007-01-15)

The second one contains my custom data flow component with my custom property that was set to an expression at design time



When my component get executed, my custom property value is still "DB189912189912.VER" and I expected "DB200701200701.VER"



Any idea ?

Custom Task - Custom Property Expression

Aug 16, 2006

I am writing a custom task that has some custom properties. I would like to parameterize these properties i.e. read from a varaible, so I can change these variables from a config file during runtime.

I read the documentation and it says if we set the ExpressionType to CPET_NOTIFY, it should work, but it does not seem to work. Not sure if I am missing anything. Can someone please help me?

This is what I did in the custom task

customProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;

In the Editor of my custom task, under custom properties section, I expected a button with 3 dots, to click & pop-up so we can specify the expression or at least so it evaluates the variables if we give @[User::VaraibleName]

Any help on this will be very much appreciated.

Thanks

Using A Excel Source To Get The Data From An Excel File Gets Null Values For A Couple Columns

Nov 19, 2007

I am using a Excel Source to get the data from an excel file to sql server 2005 table. A couple columns are coming in a double precision float, but some values have characters in them, but those values are coming out as null, even though I changed the datatype from float to unicode string. Any inputs on resolving this will be much appreciated.

Thanks,
Manisha

How To Pass The Excel Sheet Names To The Excel Source Control Through Variables

Feb 22, 2006

I am trying to get the contents of the Excel Files dynamically and dumping into the SQL Database using SSIS. Through WMI Event Watcher, I could find when one or more Excel files dumped in a particular folder and using ForEach Loop Container I was able to take all the filenames and pass it through Variables. But at the same time in the Data Flow, I have to pass each Sheet of an Excel File to the Excel Source control and export the data to my SQL Database using OLEDB Destination.

For that I need to get the names of each sheets in an Excel File and pass it to the Excel Source Control through variables. But when I give Data Access Mode as "Table name or view name variable" and provide the variable name in that, then it is giving an error message as "A destination table name has not been provided".

And at the same time, Since I was not able to provide an static Filename (as I am passing through Variables), when I tried to map the columns in the OleDB Destination, it is not allowing me to map the columns.

So all these things I should do at Run-time using Variables in SSIS. I don't want to hard-code any filenames or Sheet names. If any one of you have a solution, please share with me.







Thanks & Regards,

Prakash Srinivasan

Excel Destination Appends The Excel File Everytime A Package Is Executed

Dec 18, 2006

i have an SSIS package that exports to an excel file. This works fine. the problem is that it appends the data instead of overwriting the file. Is there any way to overwrite the file like you can with a flat file? I have to email the file everyweek and don't want to have to clear it out manually. Any help would be appreciated
