hi,
I have a datagrid. i want the user to select a row, and only one row. so
i created a template column where i placed a radiobutton...
Unfortunately this is not working, because the name of the radiobutton
is changing according to the datagrid row, so when i select a
radiobutton this won't deselect another radio button...

any idea how to do something similar
thx

Hi Joe,

I believe it's possible to achieve goal of deselecting
other radio button, when selecting one.

For any server controls in a datagrid, there are two
properties you can use, ID and ClientID. For one server
control of a column in different rows, their IDs will be
same and ClientIDs will be different. So you can try
following code

RadioButton selectedRdBtn = (RadioButton)sender;
RadioButton rdBtn;
string clientID = selectedRdBtn.ClientID;
bool selected  = selectedRdBtn.Checked;
foreach (DataGridItem item in datagrid.Items)
{
    rdBtn = (RadioButton)item.FindControl("rdBtnID");
    if(!rdBtn.ClientID.Equals(clientID)
    {
        rdBtn.Checked = !selected ;
    }
}
