Hi All,
I'm trying to set the SelectParameters of SqlDataSource from the code behind.
This is my query:
SELECT * FROM [UploadSessions] WHERE ([OwnerID] = @OwnerID)
And I need to set the value of the @OwnerID at the code behind since it is stored in an object.
How can I do it??
Thanks in advance

Hi,
I am using a grid view with parameter defined in dropdown list. the asp code is:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Pubs %>"
SelectCommand="SELECT [au_id], [au_lname], [au_fname], [state] FROM [authors] WHERE ([state] = @state)"
DeleteCommand="DELETE FROM [authors] WHERE [au_id] = @au_id">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList1" Name="state" PropertyName="SelectedValue"
Type="String" /></SelectParameters>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Pubs %>"
SelectCommand="SELECT [au_id], [au_lname], [au_fname], [state] FROM [authors] WHERE ([state] = @state)"
DeleteCommand="DELETE FROM [authors] WHERE [au_id] = @au_id">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList1" Name="state" PropertyName="SelectedValue"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
</asp:SqlDataSource>
I would like to to set the parameter assignment in my VB code in Page_Load methodWhen i am using:
SqlDataSource1.SelectParameters("state").DefaultValue = DropDownList1.Text
SqlDataSource1.SelectCommand = "SELECT [au_id], [au_lname], [au_fname], [state] FROM [authors] WHERE ([state] = @state)"I get error message saying: Object reference not set to an instance of an object.
Any ideas how I can set the select parameters (in my VB code) to use the dropdown list I have in my page?
Thanks,

Hi,How do I set the parameters of an SqlDataSource programatically?I have tried the following...dsDraftBudgetPI.SelectParameters.Add(new Parameter("@person_id", TypeCode.Int32, pID.ToString()));But that didn't work. I already have the parameter defined at design time so I don't need to create one I just want to set its value and then bind it to a ListBox to display the result.Thanks,Scott

I have a sqlDatasource with 3 parameters based on the input of 3 text boxes on the page. The datasource returns sales details for a company based on a from and to date. I am attempting to set the value of the 3 parameters in the Selecting event of the datasource control but I'm not getting any data back. If I set the values literally then I get data back. Also when I step through the code I can see the 3 parameters getting their values from the textboxes and the drop down list as they should. This is driving me insane as I'm new to .net and just can't see what is stopping me retrieving the data when using the form fields to set the datasources parameters.

View 3 Replies View RelatedI need to provide defaults and sometimes overrides for items in SQLDataSource's UpdateParameters. I am attempting to do this in a FormView's ItemUpdating and ItemInserting events as follows: //========================================================================

In the example above I am attempting to set new values for the parameters which will replace the existing values. I have found that using the DefaultValue property works ONLY if there is no current value for the parameter. Otherwise the values I specify are ingnored.The parameters of an ObjectDataSource provide a Value property but SQLDataSource parameters do not.How can I provide an override value without needing to place the value in the visible bound form element???If you can answer this you will be the FIRST person ever to answer one of my questions here!!!Thanks,Tony
I thought this would be easy. I have a repeater control and a sqldatasource control. I am trying to filter the select statement using DateTime.Now.ToString() and keep getting an invalid date string format. The control is on a content page in my asp.net site. On the master page this <%= DateTime.Now.ToLongDateString() %> works to display the current date. If I try and put <%= DateTime.Now.ToString() %> in the Default value of the SelectParameter it does not work. No intellisense either so I am assuming I am missing something. Here is the code... pretty basic really.
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="sqlDSnews">
<ItemTemplate>
<h3><%# Eval("newTitle")%></h3>
</ItemTemplate>
</asp:Repeater>
<asp:SqlDataSource
ID="sqlDSnews"
runat="server"
ConnectionString="<%$ ConnectionStrings:XXXX%>"
SelectCommand="SELECT [newTitle], [newsDetails], [dateExpires], [newsImage], [dateCreated] FROM [News] WHERE (([GroupID] = @GroupID) AND ([dateExpires] >= @dateExpires))">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="0" Name="GroupID" QueryStringField="Gid" Type="Int32" />
<asp:Parameter Name="dateExpires" DefaultValue='<%= DateTime.Now.ToString() %> 'Type="DateTime" />
</SelectParameters>
</asp:SqlDataSource>
** NOTE the DateTime does not show up in blue - if that helps with a solution **
Can you dynamically set the name of the table in the SelectCommand section of the SqlDataSource? (If it is relevant, I code in C#)
For example,
<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:Test-MySQL %>" ProviderName="<%$ ConnectionStrings:Test-MySQL.ProviderName %>" SelectCommand="SELECT * FROM TestTable">
I would like to replace 'TestTable' with the name of a table that is extracted from a string array in the code-behind.

Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">

Hi, I have created a search page which needs to perform different
search function in same page. I have setuped a sqldatasource then
manual
setup the connection string and command inside the codefile. So the
select command can be various depends on the event. The problem is
all of those setting will be reset after I click on the pageindex in
the girdview control to go to next pages. Since this gridview is linked
with this sqldatasource control, I need to restore the connection
string/command when user choose decide to view next page of data inisde
the
gridview.
I think I must have done something wrong in here becuase it will end up
retrieving the total amount of data when everytime user choose to
view next
or perivous page.
Can someone give me a hand on this ? Thanks

What im looking to do is put a checkbox on my page and if the box is checked have it add a where clause to the sql statement.
The most i have seen with selectparameters is for it to basically take the value of the given control (or whatever) and dump it in to a query.
In this case what i would like to do is if the box is not checked it has my basic query run Select * from Table
and if the box is checked i would like it to run Select * from table where status='completed'
basically a check box that shows only completed items.
wasnt sure if i could do this with just the sqldatasource control and some selectparameters or if i had to write some code.
Thanks

Hi , I am trying to write a report generator by simply using a form and then a gridview that query's the database based on what the user selects on the form. Anyways, I update the SQL parameters similar to below code. I just want to know how i can tell the parameter to get ALL values from the parameter instead of a specific value. For example if the user wanted to see ALL the records for CustomerName what would i set the parameter default value to? I tried the asterisk but that did not work. Please guide me....Thanks! MattSqlDataSource1.SelectParameters["CustomerName"].DefaultValue = "some value";<asp:SqlDataSource ... > <SelectParameters> <asp:Parameter Name="CustomerName" /> </SelectParameters></asp:SqlDataSource>
View 1 Replies View RelatedHi,
I am using Visual Web Developer 2005 Express Edition.
I am trying to SELECT three information fields from a table when the Page_Load take place (so I select the info on the fly). The refering page, sends the spesific record id as "Articleid", that looks typically like this: "http://localhost:1424/BelaBela/accom_Contents.aspx?Articleid=2". I need to extract the "Article=2" so that I can access record 2 (in this example).
How do I define the SelectParameters or QueryStingField on the fly so that I can define the WHERE part of my query (see code below). If I remove the WHERE portion, then it works, but it seem to return the very last record in the database, and if I include it, then I get an error "Must declare the scalar variable @resortid". How do I programatically set it up so that @resortid contains the value that is associated with "Articleid"?
My code is below.
Thank you for your advise!

Hello,
I am sure there is a way to do this programmatically, but it is just not sinking in yet on how to go about this. I have a page where I use a dropdownlist that goes into a gridview and then the selected item of the gridview into the detailsview (typical explain seen online). So, when selecting from the dropdownlist, the gridview uses a controlparameter for the selectparameter to display the appropriate data in the gridview (and so on for the detailslist).
My question is - I wanted to use this same page when coming in from a different page that would utilize querystring. So, the parameter in the querystring would be for what to filter on in the gridview, so the dropdownlist (and that associated controlparameter) should be ignored.
Any suggestions on how to go about this? I assume there is some check of some sort I should in the code (like if querystring is present, use this querystringparameter, else use the controlparameter), but I am not sure exactly what I should check for and how to set up these parameters programmatically.
Thanks,
Jennifer
Hi,I have a GridView which is bound to a SqlDataSource that connects to Oracle. Here's the code: <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:OracleConnectionString %>"

I have a simple gridview that loads on page load. It uses an on page sqldatasource declaration in which there's a parameter in which value is already available in cookies. I added an asp:HiddenField and set that value on PageLoad() to the value of the cookies. I then set a FormParameter in the sqldatasource mapped to that hidden field. However that appears to have no effect at all. I'm guessing the sqldatasource will only use the form field after postback.
View 2 Replies View RelatedHi everyone,
I am building a search page and am a bit stuck.
The page has an sqldatasource with no select command and i am passing the select command and parameters depending on the optionsm selected.
If a tick box is ticked and a drop down selected i need to add a parameter to the datasource and generate the select command.
then if 1 and or 2 trext boxes are filled in, add the 1 or 2 select parameters then generate the select command.
The select command is correct as far as i can tell , but the parameters are not being passed to the datasource so it doesn't select anything.
my code behind is in the page load handler and at the moment only adds the parameters in one place so i could test.
Does anyone have any idea what i have done wrong?
Cheers

Hello to all coding members!
I'm building my first ever complete website in the ASP.net VB language and I have to say, I'm pretty happy that I was able to learn from this website and to gain some ground.
Data retrieval and editing from tables and databases was very intuitive with the Visual Web Developer IDE. I even learnt simple ways to implement (and to script a bit of) login pages to make my visitors feel "at home" in my website.However, when I wanted to implement simple Business Logic into one of my ASP.net page, i happen to stumble upon a block.Business Logic: To have the server go through the whole table of storybook entries submitted by many users, but only pull out the storybook entry(s) that belong to the logged-on user.Hence, let me drill down to my specific questions:
I will be using VB. Coming from a JavaScript genre, my concern is: will putting the Business Logic code into a code-behind page (.vb) or dumping it onto the page itself have any errors or effects?
What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 with SQL Express 2005 with VB as the code behindi have one database and three tables in itfor manipulating each table i am using separate SqlDataSource() is it sufficient to use one SqlDataSource() for manipulating all the three tables ? i am manipulating all the tables in the same page only please help me

If you have a SQL server setup that isn’t using a SAN but just a normal raid array and you wanted to utilize a SAN now.
What are the steps, I'm guessing that you will need to start the services under a domain user correct?
Is it as easy as detaching the DB and then reattaching the DB on the SAN?
I'm assuming you need to map the data and log arrays from the server to the SAN correct?
I can’t seem to find any documentation on moving a server to a new SAN. Can someone post links if you have them?
Do you need ENT edition or is Standard OK .
Thanks for your help.

I'm trying to set up a new job to update a field in the table, I've managed to get the select syntax to work, but when I added an IF statement and Update syntax it didn't like it and the following error was shown:-
Server: Msg 156, Level 15, State 1, Line 9
Incorrect syntax near the keyword 'BEGIN'.
This is the syntax I'm trying to use for the job:-
USE EmployerEngagement
IF (SELECT On_Stop
FROM tblEmployer LEFT OUTER JOIN tblWP_Details
ON tblEmployer.Emp_ID = tblWP_Details.Emp_ID LEFT OUTER JOIN tblVetting
ON tblWP_Details.Record_ID = tblVetting.Record_ID
WHERE tblEmployer.On_Stop = 0
AND tblVetting.Next_Vett_Date <= GETDATE())
BEGIN
UPDATE tblEmployer
SET On_Stop = 1
END
Basically I just want to change the On_Stop value from 0 to 1 if the Next_Vett_Date is before or on todays date.
Am I using the wrong syntax for this?
Thanks
