[Solved] How to add a custom column at runtime?

[Jordan Earls]

Hello, I have a grid that is created dynamically at runtime. It is also databound.

Well, we need to be able to add a column to the grid which is filled with hyperlinks that are dynamically generated according to the RowIndex. How would we do this? I just can't figure out how access the Columns in the ItemDataBound and I can't figure out what is the proper way of adding a column that is not in the bound dataset.

Hi,

To access th columns  in the ItemDataBound/ItemCreated events use the code snippet below:

C#

  protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem dataItem = (GridDataItem)e.Item;
                HyperLink link =new HyperLink();
                link.ID="HyperLink1";
                link.NavigateUrl="Default.aspx?Key='" + dataItem.GetDataKeyValue("CustomerID").ToString() + " ' " ;
                dataItem["ColumnUniqueName"].Controls.Add(link);

            }
       }

You  can also use a GridHyperLinkColumn and manipulate the NavigateUrl in the ItemDataBound event.
