Is there any workaround that will allow me to use the RadInputManager on an MVC application?

Specifically in a block of code like:

                        <% using (Ajax.BeginForm("Search", "Events"))         
                   { %>         
                <span id="EventSearchDiv">         
                    <%= Html.TextBox("EventSearch")%>         
                    <input type="submit" value="Search" />         
                </span>         
                <telerik:RadInputManager ID="RadInputManager1" runat="server">         
                    <telerik:TextBoxSetting BehaviorID="EventSearchBehavior"         
                        EmptyMessage="Enter Event ID"         
                        Validation-IsRequired="true"         
                        ErrorMessage="Enter search text">         
                        <TargetControls>         
                            <telerik:TargetInput ControlID="EventSearchDiv" />         
                        </TargetControls>         
                    </telerik:TextBoxSetting>         
                </telerik:RadInputManager>         
                <% } %>         

I get

Control ... RadInputManager1_EventSearchBehavior' of type 'InputSettingCustomValidator' must be placed inside a form tag with runat=server.

[Solved] Disable Edit/Delete Column in Edit/Insert Mode

Hi

How can I disable the Edit and Delete Column if my RadGrid is in Edit or Insert Mode? I'm disabling the Refresh and AddNew Button OnItemDataBound but can't find the buttons for each row.

At the moment I cancel the the event in the OnItemCommand handler but would like to give the user som visual hint (greyed out) that these buttons aren't working.

Thanks for advice!

Rad Editor keeps changing my document

I'm trying to use the Rad Editor to build a document, but it seems to change my document when I switch between the design view and html view.

How can this be avoided?

I enter this

    
            <!--
        
            CUSTOM CODE HERE
        
            --> 
        
            fail 
        
            <!--
        
            CUSTOM CODE HERE
        
            --> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html> 
        
                <head> 
        
                </head> 
        
                <body>       
        
                   some text

            <!--
        
            CUSTOM CODE HERE
        
            -->

and its converted to this

    
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

                <body> 
        
                    fail 
        
            <!--
        
            CUSTOM CODE HERE
        
            --> 
        
                  some text 
        
            <!--

RadRotator image load delays ajax requests?

Hi!

I'm using the RadRotator for a thumb Image Gallery. That image gallery is within a ajaxified form which has a navigation area that enables the user to, without posting back the entire page, go to the next, previous, last or first form record (not image gallery record!). I've noticed that if I open form record 1, which the images from the image gallery take several seconds to load, and try to go to any other form record the ajax event is not fired while at least one or two images of the gallery are fully loaded. I.e., if an image takes 15 seconds to load, the user will wait at least 15s until he navigates to the next form record.

Of course this timings where an exaggerated example. My intention is to don't let the user hanged until some image is loaded to change is record, even if it's a 1s wait. Are you aware of this issue? How do I work around it?

Regards,

Rodrigo S.

            </body> 
        
            </html>

The above is the code for a master page.

What is in the contentplaceholder is quite large.

When I run the page the horizontal scroll is fine, and everything can be viewed width wise.

But, although the vertical scroll bar is there, you are able to scroll practically nothing, and it seems to be cut off at what ever height you have set the splitter to be.

Now I have set scrolling to Both on the pane, and I even tried puting the contentplaceholder in a div with scrolling, but it's just the same.

Hope someone can help!!!

Link button inside grid not triggering ajax postback

Hi

I have a grid which contains a link button inside a template column

    
             <telerik:GridTemplateColumn HeaderText="Location">  
        
                <ItemTemplate> 
        
                  <asp:LinkButton runat="server" ID="lnkAddress"></asp:LinkButton> 
        
                </ItemTemplate> 
        
                <ItemStyle Width="300px" /> 
        
                </telerik:GridTemplateColumn>

The link button is given a command argument in the item data bound event

I have tried to set up the grid so that is triggers an ajax postback when the link button is clicked. However clicking the link button triggers a full postback. What am i doing wrong?

    
               <telerik:AjaxSetting AjaxControlID="gridPolls">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="lblMapStatus" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="Map1" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting>

TreeView like a table

Hi,

Is it possible to render the TreeView control in a 'table format', something like on the picture below

http://img508.imageshack.us/img508/1060/gridtree.png

The RadGrid has a Hierarchical mode but it does not display the grid lines between nodes so the hierarchy between nodes is not so obvious so I thought maybe it is possible to do this with the TreeView control
