I set e.Canceled = true
But I want the datetime filter have the right selected item at the dropdownlist(NoFilter, GreaterThan or so)
I try to change the FilterMenu in Init, but I set it to selected and no use.
part code is

    
            <telerik:RadGrid ID="RGViewMEdia" Skin="someSkin" EnableEmbeddedSkins="false" 
        
                        runat="server" CssClass="list_one" AutoGenerateColumns="False" AllowPaging="True" 
        
                        GridLines="None" Width="800px" DataKeyNames="somefield" AllowAutomaticDeletes="True" 
        
                        AllowSorting="True" ShowStatusBar="True" AllowFilteringByColumn="true" DefaultSortDirection="Descending"

[Solved] Two RadGrid dlls

Hi Telerik,

I observed that there are two assemblies for the RadGrid usercontrol namely:

Telerik.Web.UI.dll
Telerik.WebControls.dll (RadGrid.Net2)

Why are there two dlls for the same usercontrol. Or are they different usercontrols with the same name.

Please help me out on this.

Thanks in advance
Akhila

Add Attribute of RadTextBox for OnValueChanging

hi,
I am using radtextbox to enter text. I need to show confirm box when user changed the value in the textbox. So i added onvaluechanging method like as fowllows:

    
                        function ConfirmUpdate(sender, eventArgs) {  
        
                            var oldvalue = eventArgs.get_oldValue()  
        
                            if (confirm('Are you want to Continue? ') != true)  
        
                                eventArgs.set_newValue(oldvalue)   
        
                        }

This work correctly. But i need to add this function from the code behind because of 2 reasons
1. I use this textbox for insert and update functions. When update only need to ask the confirm.
- i can handle this in script itself by comparing oldvalue and newvale
2. I need to pass myown message t the confrm box.
- For this i want to add this event from the code behind.

How can i add this function to the textbox attribute?
How can i pass message without affect the eventArgs values?

Background Color for RadEditor

Hi,
I would like to change the background color of my RadEditor. I've seen all of the posts where they say to use the code below and put the classes in the newly created css file. I've tried this and it doesn't work...it still picks up the background color of the parent page. Does anyone know a workaround for this?

Thanks

<telerik:RadEditor ID="RadEditor1" Runat="server">
   <CssFiles>
       <telerik:EditorCssFile Value="~/EditorContentArea.css" />
   </CssFiles>
</telerik:RadEditor>

RadGrid DetailTable Not Showing

Hey guys, i've been using your Telerik products for ASP.NET and AJAX development for the past two months about, and have enjoyed them very much. Usually i can solve my problems by reading extensively through the content on your site and forums, but as several hours have gone by i'm feeling a little helpless.

I have a three-tierd heirarchy grid. The first two tiers work perfectly, when expanding to the third, the grid closes back up to the first tier and never hits the DeatailTableDataBind event. I have tried this every way i can think of (programatically + declaritive) without success.

Here are my code snippets, any help is appreciated.

EDITED OUT

EDITED OUT

Once again, any help is appreciated.

EDIT --- I have found the source of my problem, i was using the pageload event to populate my grid instead of the needsdatasource event. This has fixed my problem, thanks to anyone who attempted to help!

[Solved] Databind Dropdownlist

Hi,
In this example, instead of the label, if I have a dropdown list, how do I databind it?
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplatedeclarativerelations/defaultcs.aspx

Here's my code:

    
            <NestedViewSettings DataSourceID="odsContactDetails">  
        
             <ParentTableRelation> 
        
               <telerik:GridRelationFields DetailKeyField="CrmEntityId" MasterKeyField="CrmEntityId" /> 
        
              </ParentTableRelation> 
        
             </NestedViewSettings> 
        
            <NestedViewTemplate> 
        
              <asp:Panel ID="pnlContactInfo" runat="server">  
        
              <asp:DropDownList ID="ddlPhones" runat="server"  DataTextField="Phone" DataValueField="Phone"/>  
        
              <asp:DropDownList ID="ddlEmails" runat="server" DataTextField="Email" DataValueField="Email"/>  
        
              </asp:Panel> 
        
            </NestedViewTemplate> 
        
            .....  
        
             <asp:ObjectDataSource ID="odsContactDetails" runat="server"   
        
              SelectMethod="GetContactInfo" TypeName="FVS.ControllerCRM.CRMDataControl">  
        
                 <SelectParameters> 
        
                    <asp:Parameter Name="crmEntityId" Type="String" /> 
        
                    </SelectParameters> 
        
            </asp:ObjectDataSource>

I have got it to work, the data is returned by the datalayer, but it is not getting bound to the dropdownlist.
Thanks in advance!
