Linkbutton for radwindow to veiw detail

[MIS-GSC]

Dear Sir,
I had use the aps page to display header information by radgrid and there is linkbutton for the one for the field, when user click the the linkbutton, the detail page related to the number , the radwindow will be prompt . In side the radwindow there are such header information and radgird to show information. All controls are read only in the readwindow.
This is the .aspx for the GridtemplateColumn of the link button

  <telerik:GridTemplateColumn    HeaderText="Document No" UniqueName="grvDocument
      <ItemTemplate>
            <asp:LinkButton ID="LnkEACCAPV_DOCNO" runat="server"
              CommandArgument=" <%#Container.ItemIndex%>"
              CommandName="ViewDocNo"   Text='<%# Bind("EACCAPV_DOCNO") %>'>
             </asp:LinkButton>
     </ItemTemplate>
     <HeaderStyle HorizontalAlign="Left" VerticalAlign="Middle" Width="135px" />
     <ItemStyle HorizontalAlign="Left" VerticalAlign="Top" Width="135px" />
</telerik:GridTemplateColumn>

This the above .aspx code-behind to show the radwindow :


Public Class EPAJournalDetail_Popup
    Inherits System.Web.UI.UserControlPrivate Sub rgdEJL_Generation_ItemCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs)

                                                                                                                           Handles rgdEJL_Generation.ItemCommand

        If e.CommandName = "ViewJNLNo" Then

             Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

            Dim row As DataRowView = DirectCast(item.DataItem, DataRowView)

            Session("A") = item.GetDataKeyValue("A")

            Session("B") = item.GetDataKeyValue("B").ToString()

            Session("C") = item.GetDataKeyValue("C").ToString()

 

            Dim dt As DataTable = EEPA.GetJNL_HR(Session("A"), Session("B"), Session("C"))    ''<--Dtatatable for radwindow's  Header inforamtion

            If dt.Rows.Count > 0 Then

               '

                Dim dr As DataRow = dt.Rows(0)

                Session("D") = dr("D")

                Session("E") = dr("E")

                Session("F") = dr("F")

                Session("G") = dr("G")

                Session("H") = dr("H")

                Session("I") = dr("I")

                Session("J") = dr("J")

                Session("K") = dr("K")

                Session("L") = dr("L")

                

                Session("DT_DETAIL") = EEPA.GetJNL_DETAIL(Session("A"), Session("B"), Session("C"), Session("F"), "N") '<--For radindow's radgrid databind

 

            End If

                RadWindow_Popup.ShowDialog(A,B,C,D,E,F,G,H,I,J ,K,L)

                

            End If

        end

end sub

There is the function of RadWindow_Popup.


Public Class RadWindow_Popup
    Inherits System.Web.UI.UserControl
Public Sub ShowDialog(A As String, B As String, C As String, D As String, E As String, _

                          F As String, G As String, H As String, I As String, _

                          J As String, K As String, L As String)

 

        Me.GetAjaxManager().ResponseScripts.Add("showDialog_" & Me.ClientID & "(""" & A & """,""" & _

                                                B & """,""" & C & """,""" & _

                                                D & """,""" & E & """,""" & _

                                                F & """,""" & G & """,""" & _

                                                H & """,""" & I  & """,""" & _

                                                J & """,""" & K & """,""" & L & """);")

        

        If IsNothing(lstJNL) = False Then

            lstJNL.Clear()                                                   'Public customer list

        End If

        lstJNL = GetData(DirectCast(Session("DT_DETAIL"), DataTable))  'Convert the Session to datatable

        rdgd.DataSource = lstJNL                                                                    'bind go the grid

end sub

 

    Public Sub rdgd_NeedDataSource(sender As Object,

                            e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles  rdgd.NeedDataSource

        TryCast(sender, RadGrid).DataSource = lstJNL

    End Sub

For the radwindow with the js to show on screen

<script type="text/javascript">
       function showDialog_<%= ClientID %> (A, B, C, D, E, F, G, H, I, J,K, L) {
           document.getElementById('<%= lblA.ClientID %>').innerHTML =A;
           document.getElementById('<%= lblB.ClientID %>').innerHTML =B;
           document.getElementById('<%= lblC.ClientID %>').innerHTML =C;
           document.getElementById('<%= lblD.ClientID %>').innerHTML =D;
           document.getElementById('<%= lblE.ClientID %>').innerHTML =E;
           document.getElementById('<%= lblF.ClientID %>').innerHTML =F;
           document.getElementById('<%= lblG.ClientID %>').innerHTML =G;
           document.getElementById('<%= lblH.ClientID %>').innerHTML =H;
           document.getElementById('<%= lblI.ClientID %>').innerHTML =I;
           document.getElementById('<%= lblJ.ClientID %>').innerHTML =J;
           document.getElementById('<%= lblK.ClientID %>').innerHTML =K;
           document.getElementById('<%= lblL.ClientID %>').innerHTML =L;

            $find(" rdgd").get_masterTableView().rebind();   //Sometime got null reference error


           var wnd = $find("<%=  RadWindow_Popup.ClientID %>");
           wnd.show();
       }

Now, the problem is Label A - L can display the variables, radgrid cannot bind any data to the grid, it is ensured that the list and the datatable with record , please help

Hello Momoko,

I'm not sure that I fully understand what the problem actually is. Could you please provide some more detailed information about it? I noticed that there is a comment in the last script "Sometime got null reference error". In order to address this problem I would recommend that you insert some diagnostic code there:

...
var radGrid = $find("rdgd"),
    masterTable;
if (radGrid) {
    masterTable = radGrid.get_masterTableView();
    if (masterTable) {
        masterTable.rebind();
    }
    else {
        alert("masterTable is undefined");
    }
}
else {
    alert("radGrid is undefined");
}
...

This will help me determine what's causing the issue.

Daniel
