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?

AutoGenerateColumns = "false" Font-Names = "Tahoma"
Font-Size = "9pt"

OnPageIndexChanging = "OnPaging" onrowediting="EditCustomer"
onrowupdating="UpdateCustomer" onrowcancelingedit="CancelEdit"
GridLines = "Both" OnRowDataBound = "OnRowDataBound" >
I define Lable in gridview that I want when users click on edit it show s some text in this lable so I wrote editcustomer metod like below:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}

I have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.
According to my columns value True / False I want to change the button Text which is on my GridView
I wrote the below code for it but it is not working :
while (Global.reader.Read())
{
if (Global.reader["Click"].Equals(true))
{
Button btnSold = (Button)e.Row.Cells[9].Controls[0];

I have a Gridview with about 6 templated columns hooked up to SQL, with a Save button below the grid.
When save is clicked, I loop through each row, and write each row back out to SQL.
Can you recommend a good way for me to tell whether the row has changed so I can avoid re-writing the row when nothing has changed?
This is not only for performance, but I also have a request to write out a "Last Modified Date" along with each record. So for that, I would need to know whether the row has changed.
I saw someone mentioned that the Gridview.RowState could be used for this, but I don't see how.
One alternative I see is to re-read each row from the database first, to see if anything changed. Another alternative might be to set a dirty-bit on each Textchanged, SelectedItemChanged, etc, for the row, but I'm not sure where to store that.
I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.
I have a gridview...
which consists of two columns...
1.status
2. button
status mey consists of two things
i)green
2)red
what my problem is..if status is green...then the button label in its next column should change to stop.
if status is red then the button label should change to start.
by default the button label is "button".
