Hi, I am using a RadCombo in Listview. I have assigned CausesValidation property of the RadCombo to false. But on focus of RadCombo, client validation is happening and ValidatorCalloutExtender is getting popped up.
Below is the html for radcombo :

 <tr>
                        <td align="left" class="formlabel"  >
                          Category
                          <span class="contentwarninglabel">*</span>
                            <asp:RequiredFieldValidator  ValidationGroup="UploadValidation" ID="CategoryValidator" runat="server"
                                ControlToValidate="rdComboCategory"  Visible="true" Display="None" ErrorMessage="<%$ Resources:Messages, DOCUMENT_CATEGORY %>">
                            </asp:RequiredFieldValidator>
                            <ajaxToolkit:ValidatorCalloutExtender ID="CategoryCalOutExtender" WarningIconImageUrl ="~/Images/icon_oops.gif"  CssClass="customCalloutStyle" HighlightCssClass="customCalloutStyle"
                            runat="server" TargetControlID="CategoryValidator" >
                            </ajaxToolkit:ValidatorCalloutExtender>  


                        </td>
                        <td  class="formcontrol"  align="left"  >
                            <telerik:RadComboBox
                                    ID="rdComboCategory" runat="server" AllowCustomText="false" Width="128px" AutoPostBack="true" CausesValidation="false"
                                    CloseDropDownOnBlur="true" CssClass="formlabel2controls"
                                    EnableItemCaching="true" HighlightTemplatedItems="true"  
                                    MarkFirstMatch="true" DataTextField="CategoryID" DataValueField="cATEGORYnAME" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" OnClientFocus="return false;"  >
                            </telerik:RadComboBox>
                 


                      
                                    <asp:LinkButton runat="server" CssClass="contentlinks" ID="AddCategory"   >New</asp:LinkButton>
                                      <div class="panelCSS">
                                     <div id="pnlModalPanel1" style="display: none">
                                   
                                     <asp:UpdatePanel ID="UpdatePanel2" runat="server">
                                            <ContentTemplate>
                                        
                                            <uc1:Category ID="ucAddPopup" runat="server" />
                                        
                                        </ContentTemplate>
                                        </asp:UpdatePanel>
                                        </div>
                                   </div>
                                    <ajaxToolkit:ModalPopupExtender TargetControlID="AddCategory" PopupControlID="pnlModalPanel1"
                                        BackgroundCssClass="modalBackground" runat="server" ID="mdlpopupAddevent">
                                    </ajaxToolkit:ModalPopupExtender>
                       </td>

HI
I have a RadTreeView inside RadAjaxPanel, I also have a textbox and button inside AjaxPanel, when the user clicks the button, Server side method executes and find appropriate node according to the text in textbox and select the first item.I want to scroll to selected node and I use ScrollIntoView with the following format:

<script type="text/javascript">
function OnResponseEnd(sender, arguments)
{
      var treeviewInstance = <%=RadTreeView1.ClientID %>;
      var selectedNode = treeviewInstance.SelectedNode;
       if (selectedNode != null)
       { 
          selectedNode.ScrollIntoView();
       }
}
</script>

<radA:RadAjaxPanel
    ID="RadAjaxPanel1"
    runat="server"
    ClientEvents-OnResponseEnd="OnResponseEnd">
</radA:RadAjaxPanel>

But it doesn't work and it can not find treeviewInstance.SelectedNode. What should I do?

Hello, 

I have a small question, about the SortExpression in a GridTemplateColumn.
In fact, I have a SQL table [Action] and a table [PlanActionNiveauDeRealisation]. Like this an [Action] can have a lot of [PlanActionNiveauDeRealisation].

So, I put a RadGrid with all my [Actions] and in the last columns I put this : 

In the ItemDataBound, I put : 

Like this, it's perfect, I have a nice RadGrid with the last [PlanActionNiveauDeRealisation] of each [action].

Just, I would like to make some sorting with this last column : [lastNiveau], but i dunno what to put in the SortExpression...

Do you have any idea?


Thank you

Hi,

I am using version 2009.2.826.35 and I am unable to update to the latest version at the moment. There is a bug in this version when the RadComboBox gets placed in a user control and it is set for Load On Demand.  Even though the RadComboBox has the AutoPostback set to true, the postback does NOT occur when the user highlights the text in the RadComboBox and clicks delete or backspace.

I have access to a later dll (2010.1.519.35) and I verified that this bug was fixed in this version. However, as I mentioned before, at the moment we don't want to update to the latest dll. Are there any other work arounds that can fix this bug?

Here is a link to a demo project that shows the bug (link expires on Jan 16 2011): Sample Project
Thanks,

Hi, I have a simple page with RadGrid above two RadListBox controls that are supposed to be populated with different items based on which item is selected in the grid.

No matter what techniques I try, RadListBox controls appear to be empty on the page.  I am currently trying to use simple method shown here:

http://www.telerik.com/help/aspnet-ajax/listbox-working-with-items-server-side.html

Basically manually adding an object of type RadListBoxItem directly to the RadListBox in question, but the box remains empty on the page, any tips?  Maybe grid is throwing it off in some way?  How do I refresh it?

I have a Radgrid with checkbox template column for puropse of select all rows functionality. but right now whenever i hover through the header checkbox im getting the drag and drop cursor for drag & drop but i want thearrow cursor for that.
Any help is appreciated.

Hello,

Does Telerik have anything like Dart's LiveControls for ASP.NET (http://www.dart.com/pwlc_overview.aspx)? I'm new to Telerik and am currently working on a big project which will require a good deal of client to server  interaction. Looks like the best solution other than potentially LiveControls is to write JavaScript in order to avoid postback caused screen flickering. Any suggestions for this issue or getting to know Telerik?

Thanks
