Master Pages - Getting Error / Could Not Find Control 'TextBox1' In ControlParameter 'date_con'

Jun 3, 2010

I have a master page that divides the main content into two areas. There are two asp:ContentPlaceHolder controls in the body section of the master page with IDs cphMain and cphSideBar respectively.

One of the corresponding content pages has a control in cphMain that needs to refer to a control in cphSideBar. Specifically, a SqlDataSource in cphMain references a TextBox in cphSideBar to use as a parameter in the select command. When the content page loads the following run-time error occurs:

Could not find control 'TextBox1' in ControlParameter 'date_con'.

Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

[code]....

I kinda know what the problem is... ASP.NET does not like the fact that the SqlDataSource and TextBox are in different asp:Content controls within the content page.

As a workaround, I have another TextBox in cphMain with the SqlDataSource which has Visible=False. Then in the Page_Load() event handler the contents of the TextBox in cphSideBar is copied into the contents of the non-visible TextBox in cphMain.

Forms Data Controls :: Using Gridview SelectedIndex In ControlParameter?

Mar 1, 2011

I am having a problem with using A Gridview SectedIndex or value in a sql ControlParameter. When I select the row it does what I need it to except it shows that there is no data.

but if I add Default Value of 1 the data shows up, but it needs to read from the Gridview.

[Code]....

I even added sqlDataSource.DataBind() in the SelectedIndexChanged Event to see if that would fix it but - No! I used it with a DropDown and it worked only when I use AutoPostBack = true of course.

Forms Data Controls :: How To Find The Row Of A Gridview Which Contains A Control That Fired An Event

Dec 20, 2010

I have a Gridview which contains templated column that has 5 checkboxes in it. When you click on one checkbox, I want to uncheck the other 4.

I am using the Item Template for this. I don't want the user to have to Select a row, before clicking on the checkboxes. Here is my non-working code to uncheck the other checkboxes. I realize it's not "SelectedRow" that I want since there's no selected row, so how do I find the row containing the checkbox that fired off CheckChanged?
