Hi Bharat,

When creating a RadGrid on Page_Load event, the columns or detail tables should be added to the corresponding collection first and then values for the properties of this instance should be set.

C#:

private void AddColumnsInRadGrid()

{

RadGrid1.Columns.Clear();

if (parentcompany_id == 2840)

{

GridBoundColumn col1 = new GridBoundColumn();

RadGrid1.Columns.Add(col1);

col1.HeaderText = "Registration Date";

col1.DataField = "Registration_Date";

col1.SortExpression = "";

col1.DataFormatString = "{0:d}";

col1.ItemStyle.Width = 100;

GridBoundColumn col2 = new GridBoundColumn();

RadGrid1.Columns.Add(col2);

col2.HeaderText = "Traffic Source";

col2.DataField = "Promo_Code";

col2.SortExpression = "Promo_Code";

//Similarly correct the rest of the code

}

Thanks,
Princy
