FindControl on GridView Cell returning null

Group,

This is the problem I am facing (VS2005):

- I do a GridView1.DataS ource = DataTable and GridView1.DataB ind()
- then I add checkbox coltrols to a selected few cells of the GridView:

CheckBox cb = new checkBox();
cb.ID = "cbSelect";
GridView1.Rows[j].Cells[k].Controls.Add(c b);

Every thing works fine and I am able to see the checkboxes on screen.
The user is suppose to select the checkbox, which ever is applicable
and is suppose to click a button for further processing.

On click of the button, I try to fetch the checkBoxes by doing
FindControl on the appropriate cells:

CheckBox cb =
(CheckBox)GridV iew1.Rows[j].Cells[k].FindControl("c bSelect");

But I always get cb as null. Any idea what might be wrong here ?
Yes, on button click, I check for the controls *before* reassigning the
datasource again.

Briefly stated, my problem is accessing and 'setting' properties of a label control declared in the template of another control noting that the other control is an instance of the beta 2 DetailsView control which supports a PagingTemplate. Somewhere I grabbed some declarations for a PagerTemplate to display paging as: <<First < Prev Next> Last>>

I have seen the following behavior: when issuing a Page.FindControl() for a control which exists in an item template (from within an ItemDataBound() event, for example), I get nulls back regularly. Has anyone seen this before? It's pretty aggravating to have to iterate through the controls in each grid cell to find the ones I need, especially since finding those cells is not always easy. Here's my ItemDataBound() handler: private void...

Hi, I have a very frustrating problem that I have researched for countless hours to no avail. There are many posts asking very similar things, however none usefull in my situation. I am using VS 2005 (ASP 2.0) and VB .NET. I have a page with a datalist, a gridview and then other data controls, nested in that order. This all works great, and produces a nice looking page, but I cannot for the life of me figure out how to reference

HI all, I'm returning a dataset to a gridview control. When the gridview asp.net control is populated from the returning dataset some of the cells remain empty. This is expected as some data in the dataset is empty. The cells that are empty, in the gridview control, I would like to have the value of 0 (zero) inserted. Is there a default cell value property or something similar for the asp.net gridview control. So if no data is...

Hi. I'm ripping my hair out. I'm in VS 2005 Framework 2. I have one website with a gridview with some template fields. I'm using the footer row to insert records. For this discussion there is a textbox and a linkbutton in the footer row. In the click event of the linkbutton an example of what I'm doing is this: Dim txt as textbox = GridView1.FooterRow.Cells(0).FindControl("TextBox1")

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
