How To Populate Table From Dropdown List?

Oct 18, 2005

Hi,I have table (tbl_a) that get it values form three Dropdown List and the PK of this table is FK in different table(tbl_b).Since tbl_a get its values from three Dropdown List the number of rows in this table is limited to the number of combinations the three Dropdown List is offer (in any case the number of raws in that table will be final).Assuming tbl_a and tbl_b are both empty.
The problem is that if i want to insert row to tbl_b i have to check first if there is a row that holds the values (or combination of values) i am getting from the Dropdown List in tbl_a .Then, if such row is exist i have to get the PK of that raw and insert it to tbl_b (as FK),if such row does not exist, i have to insert it and then get the PK of this row and insert it to tbl_b (as FK).
In the end, tbl_a will have all the combination the three Dropdown List can offer so checking if raw exist in this table will not be necessary.
In my opinion this is not effective way to do that.Can someone offer me better way to do it?
Thanks

Dropdown List Width

May 11, 2007

Hi everybody,

I created a multivalue parameter in SSRS 2005 SP2, but the problem is that the width of the dropdown list is too small to fit my data (I'd like to avoid scrolling horizontally).

Is there any way to configure this?

Thanks in advance for your help.

Parameter DropDown List Grayed-out

Dec 12, 2007



I am building a report with several search parameters; three of which are dropdown boxes each populated by a data set. I wanted something more user-friendly than the default "(Null)" in the dropdown, so for each data set, it returns a result set UNIONed with " N/A" to show up first as the default.

For some reason, when the report loads, the first dropdown populates just fine and does indeed have the default value " N/A" but the other two dropdowns are grayed-out. Until you change the first dropdown (to anything, apparently it doesn't matter what you change it to) the other two stay grayed-out. When the first is changed, the other two are populated and default to the desired " N/A" default value.

Why would it do this, when it didn't do it before; i.e. when the default for all of them was simply null. The dropdowns are not dependent on each other; they don't depend on other parameters for their values. Any help would be appreciated.

Special Characters In A Dropdown List

Nov 2, 2006

I have a web form that needs to be bilingual. It contains several dropdown lists. The "text" and "value" for each item in the dropdown list is retrieved from a database. The logic reads the database and then populates the various dropdowns with logic such as:

dim newItem as new ListItem(textString, valueString)

theDropDown.items.add(newItem)

The problem that I am having occurs when the textString needs to contains special characters such as accented vowels or an "n" with a tilde. I have tried populating the database with HTML-formatted strings such as "Avi&oacute;n", hoping that this would display "Avion" with an accute accent over the "o". Unfortunately it displays "Avi&oacute;n".

How do I get dynamically-created dropdowns to display special characters? If the answer is to simply store the special characters directly in the database, then the question becomes how do I get the special characters into the database? I tried to figure out how to write a T-SQL command such as

update tablex set SpanishName = 'Avion' where id=999

but I can't figure out the syntax to insert an accented 'o' into the string.

Thanks.

Separate Dropdown List Selectedvalue Into Two Fields

Aug 1, 2006

i have two columns in a "release" table that i concatenate on my aspx page into one value for my dropdown list.  for example, my database columns might look likeMajor: 3 | 3 | 4 | 4 | 5Minor: 1 | 2 | 1 | 2 | 1and my drop down list text like3.1 | 3.2 | 4.1 | 4.2 | 5.1my question comes when trying to take the drop down list's selected value and splitting it back into two fields so that i can use it for another query.  how can i split my "major" and "minor" version numbers back up so that i can run a query similar to:SELECT * FROM [Version] WHERE (([Major] = @Major) AND ([Minor] = @Minor))but only having the one parameter of: <asp:ControlParameter ControlID="ddlVersion" Name="Version" PropertyName="Text" Type="String" /> where the selected value has a string of "<major>.<minor>" (where the numbers are separated by a period)?

Populate Dropdown List With Dimension Hierarchies

Dec 17, 2006

Hi,

I am currently trying to develop an application which would help in retrieving data from cubes (Microsoft Analysis Services)! The user would not be accessing the Business Intelligence Studio, etc. but would be viewing the data from a custom made application developed in VB.Net2005.

While implementing this, I want to populate the drop-down-list in the VB(.Net) Form, by retrieving the various hierarchies in the dimensions of the cubes (along with dimensions if possible). This should be done dynamically and in real-time!

Can you please help in implementing this? Any code/method, etc would be highly appreciated!

Thanks in advance.

Best wishes!

(Software : SQL Server 2005 Enterprise Edition (with Analysis Services and BI Studio), VS.Net 2005 Enterprise Edition, ADOMD.Net)

Without Checkbox Leftside Of The Dropdown Value List Of The Parameter

Feb 5, 2007

Hi,

I believe somebody know the reason. Please help me on it!

I plan to pass a multivalued parameter from my web application to the server report, and let user select the value(s) from the value set. But when I run the report, there's no checkbox leftside of the values, that means user has no choice on this parameter.

Is there any way to do it?

Thanks,

ForEach File In Folder - Missing From Dropdown List

Jun 28, 2007

I'm working through the SSIS tutorial, and am on lesson 2.
This says
"Double-click Foreach File in Folder to reopen the Foreach Loop Editor.

Click Collection.

On the Collection page, select Foreach File Enumerator."

The drop down only contains

foreach ado enumerator
foreach ado.net schema_rowset.enumerator
foreach from variable.enumerator
foreach nodelist.enumerator
foreach smo.enumerator


How do I get the "foreach file in folder" to appear in the drop down list?

Firefox In Mac Fails To Render Scrollbar In The Multi-value Parameter Dropdown List Generated By ReportViewer.

Mar 10, 2008

Our clients working with the Firefox browser on a Mac are unable to use the Multi-Value parameter drop down lists that the Report Viewer control generates. Of course I realize that the multi-select dropdown lists are not really dropdown option lists using the standard HTML select tag, but are rather tables within div tags with cells that contain spans, inputs, and labels.

Originally the report viewer displayed these lists in the wrong position within Firefox on any platform (Mac or PC). Furthermore, there were other visibility problems with those lists that made it virtually impossible to select a checkbox within the list. Fortunately, Microsoft fixed this problem with the latest version of Report Viewer, which we downloaded from the following link:
http://207.46.19.190/downloads/details.aspx?FamilyID=cc96c246-61e5-4d9e-bb5f-416d75a1b9ef&displaylang=en

So currently we have SQL Reporting Services Report Viewer 9.0.21022.8 installed on our web server. And the dropdown lists do appear as expected, and they work properly in Firefox on a PC.

But, when the control is rendered in Firefox on a Mac, the list is not scrollable. The scroll bar that should appear on the right-hand side of the dropdown list, which would enable users to select values toward the bottom of the list, does not appear. That scrollbar is missing in Firefox.

This is likely related to a Firefox rendering issue with the overflow:auto style. There are numerous entries on the web that indicate Firefox for Mac has a problem with overflow:auto. For example:
http://www.webdeveloper.com/forum/archive/index.php/t-96958.html
http://www.daniweb.com/forums/thread44144.html
http://iamthewalr.us/blog/2007/04/20/firefox-on-the-mac/#comment-2321
http://www.errorforum.com/mozilla-firefox-error/3503-will-float-mac-firefox-scrollbars-floating-pop-up-windows.html
https://bugzilla.mozilla.org/show_bug.cgi?query_format=specific&order=relevance+desc&bug_status=__open__&id=187435


That being the case, it seems that there should be some workaround to address this, either via a style or through some alternate control. Or perhaps there is a property that we can apply to the ReportViewer control that I'm unaware of which addresses this.

If you know of a workaround, or can suggest an alternate approach that we could implement quickly, please respond. Thanks.

Subreports: Parameter Value Dropdown Shows Sum And Count Fields But Not The Actual Data Fields.

Jan 28, 2008


I have just started using SQL Server reporting services and am stuck with creating subreports.

I have a added a sub report to the main report. When I right click on the sub report, go to properties -> Parameters, and click on the dropdown for Parameter Value, I see all Sum and Count fields but not the data fields.

For example, In the dropdownlist for the Parameter value, I see Sum(Fields!TASK_ID.Value, "AppTest"), Count(Fields!TASK_NAME.Value, "CammpTest") but not Fields!TASK_NAME.Value, Fields!TASK_ID.Value which are the fields retrieved from the dataset assigned to the subreport.

When I manually change the parameter value to Fields!TASK_ID.Value, and try to preview the report, I get Error: Subreport could not be shown. I have no idea what the underlying issue is but am guessing that it's because the field - Fields!TASK_ID.Value is not in the dropdown but am trying to link the main report and sub report with this field.

Am I missing something here? Any help is appreciated.

Thanks,
Sirisha
