Hi,

I have a treeveiew control inside a radcombobox.
"OnClientNodeClicking" event of treeview I am setting the textproperty of the combobox using javascript.
I am trying to fire some event so that I can access the function in my the code behind.
I have tried "OntextChanged" & "SelectedIndexChanged" of combobox but none of them was raising the event.
If i use "OnItemsRequested" event then i am getting error "Sript control RadTreeView is not a registered script control. Script control must be registered using RegisteredScriptControl() before calling RegisteredScriptDescriptors(). Parameter name scriptControl.."

I need to load other dropdowns based on the selected tree node which is inside the dropdown.

any help will be grealy appreciated.

 <telerik:RadComboBox ID="RadComboBoxCategoryLevels"
                         Width="160px"
                         Height="150px"
                         AllowCustomText="false"
                         EmptyMessage="Any Category"
                         OnItemsRequested = "RadComboBoxCategoryLevels_ItemsRequested"                                                   
                         runat="server" >
                         <ItemTemplate >
                            <div onclick="StopPropagation(event)">
                                <telerik:RadTreeView ID="RadTreeView"
                                                     AppendDataBoundItems="true"
                                                     runat="server"
                                                     OnClientNodeClicking="OnclientNodeClickingHandler">                                                     
                                                     <DataBindings >
                                                        <telerik:RadTreeNodeBinding Depth="0" Expanded="true" />
                                                     </DataBindings>                                                     
                                </telerik:RadTreeView>                                
                            </div>                            
                        </ItemTemplate>
                        <Items >
                            <telerik:RadComboBoxItem Text="" />
                        </Items>                     
    </telerik:RadComboBox>   

function OnclientNodeClickingHandler(sender, e)
                        {
                        //debugger;
                            var node = e.get_node();                           
                                var combo = $find("<%= RadComboBoxCategoryLevels.ClientID %>");
                                combo.set_text(node.get_text());
                                combo.hideDropDown();        
                                combo.requestItems(node.get_text(),false);  
                                
                        }

I am trying to get the SelectedValue of a RadComboBox that is populated via a webservice. However, the SelectedValue is blank when I try to get the value when I postback. How can I get the selected value server side?

Thanks,
Ron

Hi, I am trying to create something similar to the "Load on Demand" tab strip example. http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx

Hi 
    I have a div and onmouseover of that div i need to show the menu and when use onmouseouts from that div i need to hide that menu i tried doing this with contextmenu and successfully show/hide menu but the problem is when user onmouseouts to click the menu the menu gets hidden. I need to keep showing menu onmouseout but if user goes away i need to hide.

</div>

 

 

<script type="text/javascript" language="javascript">

 

 

 

 

function showMenu(e)

 

{

 

var contextMenu = $find("<%= mnuDemographic.ClientID %>");

 

 

 

if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget)))

 

{

 

 

contextMenu.showAt(e.screenX - 40, e.screenY - 120);

}

 

 

 

// $telerik.cancelRawEvent(e);

 

 

 

}

 

function hidemenu(e)

 

{

 

var contextMenu = $find("<%= mnuDemographic.ClientID %>");

 

 

 

if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget)))

 

{

 

 

contextMenu.hide();

}

}

I just need to find a dropdown that resides in ItemTemplate of MasterTableView: Colums 3 of RadGrid. I just tried following:

DropDownList

temp = ((DropDownList)RadGridMkbzHzmt.MasterTableView.FindControl("ddlHzmt"));

It throws exception "Object reference not set to an instance of an object"

How can i get over this?

Thanks in advance...

 

 

Hi,

I have been working around with the scheduler and now I have somehow provoked the error underneith.
To provoke the error I drag-resize an appointment in week or day view. The Update method in my custom SchedulerProvider is run without a problem and after that the page just displays the error.

Any Idea what I am doing wrong to make it fail in the Telerik.Web.UI.AppointmentControl.Initialize() method?

 

Server Error in '/' Application.

Quick question.

What are the defaults for OutputCompression, EnableScriptCombine and EnableStyleSheetCombine for these controls and how does debug=false in the config affect the default if at all?

Thanks
Matt

I have a RadGrid that has two columns that are invisible to begin with.
When I click a button outside the Grid I want the columns to become visible.
I know that there is a property in the grid (e.g. this.RadGrid1.Columns[0].Visible = true;), but the columns still won't show after setting them to visible in the button click event.
The interesting thing is that if I click the "Refresh" button within the Grid after having clicked the external button the columns show up.
I tried this.RadGrid1.Rebind(), but that doesn't do it either. It seems like only the "Refresh" in the Grid itself makes the columns visible.

How do I get the columns to become visible on the button click outside the grid?

This has got to be something fairly obvious, but I just don't see it.

Any help is appreciated.

I have run into an issue with the timeline view. I set the properties as follows.

About two months ago I was told RTL is not officialy supported. Do you support it now officialy ?
