Re: Creating Hyperlink in DataGrid Column

Tech-Archive recommends: Speed Up your PC by fixing your registry

Hi Elton,

I'm getting an error:

"System.ArgumentOutOfRangeException: Specified argument was out of the range
of valid values. Parameter name: index" with regard to the statement:

HyperLink link = (HyperLink) nameCell.Controls[0];

This cell is a BoundColumn. Any ideas what could be happening here?

Thanks.
