Template Columns Controls

[Guest]

I have datagrid , i edited the template column by adding checkbox on in
templateheader and one in templateitem

the problem i have i can not get access to the checkbox at runtime , i did
this to get them but not worked:

string ClientID = "";
foreach(DataGridItem item in dgAddresses.Items)
{

CheckBox chk = item.FindControl("chbAll") as CheckBox;
if(chk != null)
ClientID = chk.ID;
else continue;

}

how can i get access to them?

It should have worked. Make sure you databind the datagrid before you
attempt looping through its items and also add a condition to examine the
datagrid itemtype first, e.g.
foreach (DataGridItem item in dgAddresses)
{
switch (item.ItemType )
{
case ListItemType.Header:
// find the chbAll control
break;
case ListItemType.Item:
//find the individual controls
break;
}
}

I have a sample where I used the event handler of the checkbox to process
whatever action needed instead of looping through the entire datagrid:

Hi,

You may also want to change this:

CheckBox chk = item.FindControl("chbAll") as CheckBox;

to:

CheckBox chk = (CheckBox)item.FindControl("chbAll");

I can't say I've ever heard of "as" in C#.
