Radbutton CommandArgument Open New Tab

[Mohammed]

Hi,

I have a radbutton which when pressed updates some profile variables and then redirects to another page. What I am trying to achieve is to have a new tab open when the button is pressed instead of the same tab redirecting to another page.

The radbutton is located within a GridTemplateColumns in a Ragrid if that makes a difference:

<telerik:RadButton ID="SelectC" runat="server" Text="Select" CommandName="Select"                                  CommandArgument='<%#Eval("Rulcode_Child")+","+ Eval("UIO_ID")+","+ Eval("PERSON_CODE")%>' >
</telerik:RadButton>

protected void gridEnrolmentsCourse_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == "Select")
    {
        string[] commandArgs = e.CommandArgument.ToString().Split(new char[] { ',' });
        Profile.Rulcode = Convert.ToInt32(commandArgs[0]);
        Profile.UIOID = Convert.ToInt32(commandArgs[1]);
        Profile.Percode = Convert.ToInt32(commandArgs[2]);

        if (ViewState["PreviousPage"] != null)
        {
            //Open new tab here somehow
            Response.Redirect(ViewState["PreviousPage"].ToString());
        }
    }
}

Solved.

     string url = ViewState["PreviousPage"].ToString();
     string script = string.Format("window.open('{0}');", url);
     ScriptManager.RegisterStartupScript(Page, Page.GetType(), "newPage" + UniqueID, script, true);
