Check if GridView Column Exists

If you have a DataRowView you can use the following extension method to check if a GridView column exists:

public static bool ColumnExists( this  DataRowView rowData,  string  fldToCheck)
{
return rowData.Row.Table.Columns.Contains(fldToCheck);
}

Normally, you would use it on RowDataBound event, e.g:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
DataRowView rowData = e.Row.DataItem as DataRowView;
string  fldToCheck = "MyFieldName";
if (e.Row.RowType == DataControlRowType.DataRow)
{
      if (rowData.ColumnExists(fldToCheck) ...
