Getting values form RadGrid in content page

[Keven]

Hello,

I have 4 RadGrids in editmode in my content page and they are in a multipageview. My problem is when I want to update all my grids. They are in my content page and i've made a button to update the grids in the masterpage. Is there a way to access the values of the grids in my content page from the masterpage or to call the update commande of the radgrids from the masterpage.

Thanks

Keven

Hello Keven,

Following is a sample code to achieve your requirement. Inside 'OnClick' event of button in MasterPage, access the ContentPalceholder first and then using FindControl method get each control like below.

ASPX: (content page)

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" >
      <telerik:RadPageView ID="Pageview1" runat="server">
       <telerik:RadGrid ID="RadGrid1" runat="server" AllowMultiRowEdit="true">
         <MasterTableView CommandItemDisplay="Top" EditMode="InPlace">
           <Columns>
              <telerik:GridBoundColumn UniqueName="EmployeeID" DataField="EmployeeID">
              </telerik:GridBoundColumn>
           </Columns>
          </MasterTableView>
       </telerik:RadGrid>
     </telerik:RadPageView>
   </telerik:RadMultiPage>
 </asp:Content>

C#: (master page)

protected void Button1_Click(object sender, EventArgs e)
    {
      ContentPlaceHolder contentPlaceHolder = (ContentPlaceHolder)this.FindControl("ContentPlaceHolder1"); // accessing ContentPlaceHolder
      RadMultiPage multiPage = (RadMultiPage)contentPlaceHolder.FindControl("RadMultiPage1");// accessing MultiPage
      RadGrid RadGrid1 = (RadGrid)multiPage.PageViews[0].FindControl("RadGrid1");//accessing RadGrid
      foreach (GridDataItem item in RadGrid1.Items)//loops through each grid item
        {
            if (item is GridEditableItem)
            {
                TextBox txtbox = (TextBox)item["EmployeeID"].Controls[0];
                string value = txtbox.Text;
            }
        }
    }

Thanks for the quick reply Shinu, but unfortunately it doesn't work. It's always giving me a argument of out range exception error on item("itemname").controls(0). The difference with your example is that I don't use a inplace editmode but a editforms.

Dim temp_multi_page As RadMultiPage = Me.ContentPlaceHolder1.FindControl("RadMultipage1")

                   Dim grid_serveur As RadGrid = temp_multi_page.FindControl("RadGridServeur")

                  


                    

 

 

 

                   For Each item In grid_serveur.Items

                       If TypeOf item Is GridEditableItem Then

                           Dim txtbox As TextBox = DirectCast(item("NOM").Controls(0), TextBox)

                           Dim value As String = txtbox.Text

 

 

                       End If

                   Next

<telerik:RadMultiPage ID="RadMultiPage1" Runat="server" Height="500px"
        SelectedIndex="0" Width="100%">

Hello Keven,

Please make the following modification in the above code if you are using RadGrid EditMode as 'EditForms'.

VB.NET:

Protected Sub Button1_Click(sender As Object, e As EventArgs)
  Dim contentPlaceHolder As ContentPlaceHolder = DirectCast(Me.FindControl("ContentPlaceHolder1"), ContentPlaceHolder)
  Dim multiPage As RadMultiPage = DirectCast(contentPlaceHolder.FindControl("RadMultiPage1"), RadMultiPage)
  Dim RadGrid1 As RadGrid = DirectCast(multiPage.PageViews(0).FindControl("RadGrid1"), RadGrid)
  For Each editItem As GridEditFormItem In RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem)
    Dim txtbox As TextBox = DirectCast(editItem("EmployeeID").Controls(0), TextBox)
    Dim value As String = txtbox.Text
 Next
End Sub
