Hi everyone,

 I have a radgrid with 3 checkboxes on it. When it loads it has many rows. For some of the rows the check boxes are enabled and for other they are disabled. 

 My problem is though I don't know where to put the intelligence that determines this. That is, I don't know what event to use Load, init, something else (render perhaps)? I need the user to be able to be able to see it every time the the page loads and when they postback.

 I would appreciate any advice/suggestions/simple code-samples that you may be able to offer.

Cheers,
Al.

Hi Alan,

If the checkbox state depends on some data inside the table row, then the correct place to put the "intelligence" is ItemDataBound. If the data inside the table row does not matter, then you can use ItemCreated.

For example

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = e.Item as GridDataItem;
        CheckBox chk = item["ColumnUniqueNameHere"].Controls[0] as CheckBox;
        if (true)
            chk.Enabled = true;
        else
            chk.Enabled = false;
    }
}
