Custom GridView delete button

Question

How can I customize automatically generated command button, e.g. Delete?

I want to add a client confirmation on deleting and in the same moment I want this

You can probably do it by implementing the PreRender event for the grid.

Here is some basic psuedo code:

protected void yourGrid_PreRender(object sender, EventArgs e)
{
    GridView grd = (GridView)(sender);

    // iterate through all your rows and look for the button
    // make sure to add code to verify your rows, columns, and control bounds are valid
    for (int rowIndex = 0; rowIndex < grd.Rows.Count; rowIndex++)
    {
        LinkButton btn = grd.Rows[rowIndex].Cells[deleteButtonColumnIndex].Controls[0] as LinkButton;

        // Here you have access to the button so change it to do what you need.
        btn.OnClientClick = string.Format("return confirm('{0}?')", btn.Text);
    }
}

Also if you want it baked in you will probably need to extend the GridView and implement your own code. See the following thread:
