Popup column in Grid

[bharat kumar]

Hi,

i have a rad grid and i want to open popup to get data from web service and attach the column in grid.
in my grid auto add/edit and delete is true...

subActionTableView.AllowAutomaticDeletes = true;

            subActionTableView.AllowAutomaticUpdates = true;

            subActionTableView.AllowAutomaticInserts = true;

            subActionTableView.AutoGenerateColumns = false;

if i am using hyperlink colum then the link is not coming in add/edit popup window.

GridHyperLinkColumn hyperlinkColumn = new GridHyperLinkColumn();

            hyperlinkColumn.HeaderText = "AIPS Task";

            hyperlinkColumn.DataNavigateUrlFields = new string[] { "TaskId" };

            hyperlinkColumn.DataTextField = "EpssTask";

            hyperlinkColumn.Target = "_blank";

            hyperlinkColumn.DataNavigateUrlFormatString = "../TaskSelector.aspx?disableMaster=1";

            hyperlinkColumn.HeaderStyle.Width = new Unit("71");

            subActionTableView.Columns.Add(hyperlinkColumn);
