Hello,

Try out the following steps and let me know if it helps meet your requirement:
1) You need to add the required number of BoundColumns and the Template Columns(having textboxes,checkbox etc)
aspx:

 <telerik:RadGrid ID="RadGrid1" runat="server"  GridLines="None" AutoGenerateColumns="False" OnNeedDataSource="RadGrid1_NeedDataSource">
       <MasterTableView CellSpacing="-1">
             <Columns>
                    <telerik:GridTemplateColumn UniqueName="TemplateColumn" HeaderText="Click">
                        <ItemTemplate>
                            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridBoundColumn DataField="CustomeriD" HeaderText="Customer" UniqueName="column">
                    </telerik:GridBoundColumn>
              </Columns>
        </MasterTableView>
 </telerik:RadGrid>

2) To initially display only headers set the datasource of the grid to an empty object collection
c#:

protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
      if(!IsPostBack)
         RadGrid1.DataSource = new object[] { };
      else
        {
             //select query based on selection from the pop up window i.e., Session["CustomerID"]

        }
    }

3) On selecting an item from the pop up window, you can store the selected value in a session variable and register a client script as shown below:
c#
 

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
            DropDownList ddlList = (DropDownList)sender;
            Session["CustomerID"] = ddlList.SelectedValue;
            ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind();", true);

    }

4) You can then call a refreshGrid function defined in the Browser window  so as to pass window parameters , as shown below:
js:

function CloseAndRebind(args)
        {
            GetRadWindow().Close();
            GetRadWindow().BrowserWindow.refreshGrid(args);
        }

5) In the refreshGrid function defined in the main page, you should, in turn, fire an ajax request:
js:

function refreshGrid(arg)
           {
             if(!arg)
             {
             $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
             }
           }

6) Finally, rebind the grid in the AjaxRequest server side event:
c#:
 

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            if (e.Argument == "Rebind")
            {
                      RadGrid1.Rebind();
            }
        }
