I can´t sort the columns

[Benigno Benavides Siller]

Hi

I´m using Visual studio 2008, framework 3.5 and the new version of Prometheus.

I have a RadGrid  in a content page with the next code in asp.

<

telerik:RadGrid ID="RadGrid1" runat="server" AllowSorting="true" >

<MasterTableView Width="100%" AllowMultiColumnSorting="true" />

<ClientSettings ReorderColumnsOnClient="true" AllowColumnsReorder="true" >

<ClientEvents OnColumnResized="ColumnResized" />

</ClientSettings>

</telerik:RadGrid>

The RadGrid gets the values  in code behind when I click on a button.

My problem is when I want to sort the columns , the columns dissapear. In fact, de RadGrid dissapear.
I was trying to use an AjaxManager like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
          <AjaxSettings >
          <telerik:AjaxSetting AjaxControlID="RadGrid1"   >
               <UpdatedControls >
               <telerik:AjaxUpdatedControl  ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1"  />
               </UpdatedControls>
                 </telerik:AjaxSetting>
           </AjaxSettings>
          </telerik:RadAjaxManager>
         
          <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px"
              Width="75px">
              <img alt="Loading..." src='<%= originalAttribute="src" originalPath="'<%=" RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'
                  style="border: 0px;" />
          </telerik:RadAjaxLoadingPanel>


But I can´t get what I want.

Any suggestion?

Thanks

Hello Benigno,

Can you post a bit more info about how the grid is bound in your case? You should use advanced data-binding with NeedDataSource or DataSourceID for automatic sorting.

All the best,

This is my code in Visual basic:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

defineTable()

End Sub

Public

Sub defineTable()

 

Dim graphicD As New graphicDAO

Dim scriptString As String

Din graphicV as New graphicVO 

 

 

graphicV= graphicD.getInformation()

 

If graficaV.getError = True Then

scriptString =

"<script language=javascript type=text/javascript>var message='ERROR';alert(message); window.location='Default.aspx';</script>"

Response.Write(scriptString)

 

ElseIf graphicV.getError = False Then

If graphicV.getIsEmpty = True Then

Me.lblMessage.Visible = True

Else

Me.lblMessage.Visible=False
Me.RadGrid1.DataSource = graficaV.getInformation

Me.RadGrid1.DataBind()

 

End If

End If

End Sub

I have two classes called graphicDAO and graphicVO. IN the class graphicDAO I use a function ,getInformation() and with this function  I get the values for the Grid  returned as  a property of the  object (graphicV.getInformation) .

Thanks

Hello Benigno,

From your code snippets I see that you use simple binding to bind the grid content (calling DataBind()). As suggested in our previous reply, I suggest you modify your binding logic to use advanced binding through the NeedDataSource event. See these articles for more info:

http://www.telerik.com/demos/aspnet/Grid/Examples/Programming/NeedDataSource/DefaultCS.aspx

http://www.telerik.com/help/aspnet/grid/?grdEventSequence.html

Note that you can refresh the grid content at some page of the lifecycle assigning new data source and invoking its Rebind() method.
