I'm trying to figure out how to implement a filter on a template column that has multiple checkbox values.  

Scenario
The data source that I'm using for my grid control is an ObjectDataSource that is returning a list of business account objects.  This particular column represents a List<> of cost categories objects (contains a name field and boolean isUsed property) that the business account can be used for.  The customer wants all available cost categories displayed as check boxes with the ones associated to the current business account to be checked.  They want to be able to filter this column by selecting one cost category names from a drop down and it to filter the rows to only those that have that cost category checked.

The code below is from the current page (I removed industry specific terms for the sake of clarity). The selected cost categories are being correctly checked during the ItemDataBound and the filter template is being displayed correctly.  However, when I select a value I'm getting the error message following the code.

Can someone point me in the right direction?

Hello!

Sure - I can define my own xpath, datavalues etc..but there must be a DEFAULT xml schema setup for this control?

Please..someone tell me where I can get the FULL xml schema definition for RadMenu.
This demo is pathetic - sorry...but it is.

http://demos.telerik.com/aspnet-ajax/menu/examples/programming/xmldefinition/defaultcs.aspx

It states you can use the RadMenu.GetXml() method - but that method does NOT output all of the menu attributes as I'd expect..like url, flow, enabled..

Thanks!

The sitemap control has a font property which can be bolded, but what if I want only certain entries bolded, or even the font color changed.  Can that be done?

Hi,

i have two Template columns in a RadGrid, a RadDatePicker control in one and a RadCombobox in the other.

can any one please help me.

I have a situation where we want to use a search method that is already in place for post backs on certain pages, however, they want to use the same method but use it for onkeypress to search while the user is entering to return matches, etc.  obviously the onkeypress is client-side and my method is in a class which I can call from the code behind which is server side. Suggestions on this?

For some reason IE is not rendering the 'RepeatColumns' Correctly.  My sitemap has 4 groups so I have the RepeatColumns set to 4 like so:

However in IE only 3 columns show up and the 4th is on the next line.  Firefox, Chrome, and Safari all render this correctly.

If I set the columns to 5 instead of 4 it works correctly, but then the spacing is wrong because it is compensating for an additional column. 

Any ideas?

I would like to offer users the ability to select from a list of videos, and upon clicking, show that video in a preview window.  Ideally, this would be docked, and would open for the video and then close once the video was completed.  Is this possible?  Are there any demos?

when i test the RadSpell this error occures how could i solve this problem please help me.
Thank you.

Hello,

I have created one page which have Treeview and other controls. Child node data populating using web-service method.

 <ajaxToolkit:ToolkitScriptManager runat="server" ID="RadScriptManager1" AsyncPostBackTimeout="18000">
</ajaxToolkit:ToolkitScriptManager>
<telerik:RadScriptBlock>
<script>
 var allowDragDrop = "<%= allowDragAndDrop%>";
            var SelectedType;
            function nodePopulating(sender, eventArgs) {
                var node = eventArgs.get_node();
                var context = eventArgs.get_context();
                SelectedType = document.getElementById('<%=hdnSelectedNodeType.ClientID %>').value;
                context["ParentID"] = node.get_value();
                context["AllowDragAndDrop"] = allowDragDrop;
                context["SelectedType"] = SelectedType;
            }
        </script>
</telerik:RadScriptBlock>

Treeview is located in one Update panel and Other controls are located in Second Update panel like below.
<div ID="Left">
  <asp:UpdatePanel ID="upLeft" runat="server" UpdateMode="Conditional">
       <ContentTemplate>
             <telerik:RadTreeView ID="tvNodes" runat="server" EnableDragAndDrop="false" ExpandAnimation-Type="OutExpo"

                                        <WebServiceSettings Path="../ManageNode.asmx" Method="GetNodes"></WebServiceSettings>
                                    </telerik:RadTreeView>
    </ContentTemplate>
   </asp:UpdatePanel>
</div>
<div id="right">
     <asp:UpdatePanel ID="upright" runat="server" UpdateMode="Conditional">
         <ContentTemplate>
           <asp:Button ID="btnSave" runat="server" OnClick="btnSave_Click" Text="Save" ValidationGroup="surveyValidate" />
            .......................... <!-- Other Controls -->
         </ContentTemplate>
       </asp:UpdatePanel>
</div>

When I clicked on node then I have loaded selected node-data into the right side controls which is in upRight update panel, when I perform click "btnSave" then we are updating node information and then call upleft.Update() to update treeview node,
after that If I want to populate child nodes for selected node then it will gives error like eventArgs.get_context() is null.

if upleft.Update()  is commented then perform above operation then the error is not occurred. But I have to update the Treeview information as well.

Please help me out why this error is occurred.

Thanks,
