Out of Index error on edit

[Michael]

I'm getting the following error when I click on the edit link in my grid.  Any help would be appreciated.

Specified argument was out of the range of valid values.
Parameter name: index

Hi Michael,

You could resolve your issue by adding additional condition in the ItemCreated event checking if the e.Item is not in edit mode. The corrected code is below.

if (e.Item is GridDataItem && !e.Item.IsInEditMode)
{
    GridDataItem item = (GridDataItem)e.Item;
    DataRowView row = (DataRowView)e.Item.DataItem;
    item["FullName"].Text = row["FullName"].ToString();
}
