RadCombobox On Load issue with Item Template

Hi,

I'm following this demo :

http://demos.telerik.com/aspnet-ajax/combobox/examples/overview/defaultvb.aspx

My binding is correct but the item template table is always showing "Loading..." without displaying any result no matter what.

Even If I remove the table inside inside ItemTemplate

I always get "Loading..."

I'm using Telerik version 2014.1.225.35

Any help please ?

Thanks

RadGrid inside RadDataForm

Hi,

I'm implementing a RadGrid inside the RadDataForm. The purpose is to collect a list of objects that are tied to the main object that the dataform is collecting information from. I'm taking in this subgroup with textboxes and then store it in a list of objects in session and posted back onto the RadGrid. However, the problem I'm running into currently is that I'm also trying to incorporate the RadGrid InPlace edit mode, and whenever I go to try and edit the object, the grid disappears. However, it seems like if I refresh it, it does go into edit mode but will not display the values in the columns. I've configured the NeedDataSource on the RadGrid but it doesn't seem to call it on the pageload or postback functions even though I specifically tell it to call these functions in the front-end with OnNeedDataSource and so forth. I've also tried to explicitly call OnItemCreated and OnItemDataBound to see if it hits the code behind but the grid doesn't seem to be referencing those functions either. What's the best approach to implement this functionality? I know you can reference the naming container of the object but I can't seem to get the RadGrid to reference its naming container, so not sure what I'm doing wrong.

            <telerik:GridBoundColumn   
        
                  DataField="PHONE"   
        
                  UniqueName="PHONE"   
        
                  HeaderText="Phone" 
        
                  DataFormatString="{0:###-###-####}">  
        
            </telerik:GridBoundColumn>

however, it seem that the value is not formmatted...what I'm doing wrong?

Sort image (arrow) does not show up when using SortExpression

I have a RadGrid with column ->

<telerik:GridBoundColumn UniqueName="Description" HeaderText="Description" DataField="ShortDescription" HeaderStyle-Width="15em" SortExpression="ProductCatalogDescription" FilterControlWidth="16em">

Whenever the 'SortExpression' is set, the Ascending/Descending image (up/down arrow) is missing
when you cilck on the column header. If I remove 'SortExpression', then it shows up.

Is this a bug?

RadGrid + Entity Framework executes Query 3 times

Hi,
My Environment: VS 2010 SP 1, EF 4/5, Teleri RadControls AJAC Q3 SP1 - 12.3.1205.0

Protected Sub RadGrid1_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

Dim d As New Ares4AgsmEntities

Dim q = From i In d.Computer

Select i.SamAccountName, i.SerialNumber

RadGrid1.DataSource = q

End Sub

Bind RadGrid to EF context executes the same query 3 times (see SQL Profiler). I also bind GridView to EF context this executs query 1 time.
Bind RadGrid to EntityDatasource this executes the query 1 time.
Whats the problem ? Is this a default behavior ?
