Multicolumn RadComboBox losing the scope of selected index item when you revisit the selection item

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multicolumncombo/defaultcs.aspx

Please find the attached screenshot.

I just followed the same code for implementation, but the
chosen value get changing to the first item ‘Ana Trujillo’.

The above scenario only happening whenever exist the
duplicate values of ‘Title column‘.

Ex: In my scenario ItemDataBound event
Text is ContactName and Value is Title.

The ComboBox data binding happens only once on page load
in page life cycle.

The failure case at the movement is considering the
selection item get changes the item to first instance of the duplication of the
‘Title’ column.

Any help please.

RadListView does not re-create items after postback

Hi,

I have a custom control which works as a pager: it's a RadListView in which each element is sort of a button which postbacks

This ascx is used in 2 projects; in the first one everything works like a charm: when a button is clicked, the event is raised and handled by the ascx
In the second one, however, something went wrong: clicking on the button does the postback, but does not fire because, I've discovered, the target isn't there no more

In practice, in project 1 the RadListView re-create its items (as stated here), while in the second one items are not created after the button's postback
Since the button isn't there, __EVENTTARGET is null and the event fails

Both projects are quite knotty, since have a main page, the pager ascx and the button (which is an hyperlink child class object), and I can't post'em publicly.. but a smaller project would of course work, such the project 1 does, so I can just wonder what went wrong without reproducing it

I think there's little I could broke since the ItemCreated should occur before the page_load, but clearly something is different and I don't know what could it be.. any ideas?

Thanks

Page Size Dropdown Stops Working

I have a RadGrid with paging and sorting enabled. On first load, the page size dropdown works well - i can select a new page size. But once i do so, the page size selector stops working, although the page size i previously selected is remembered. There doesn't seem to be any script errors on the page. What can cause such behaviour?

Model Binding: SelectMethod defined in a Business Object.

I am trying to use the ASP.NET 4.5 Model Binding features of RadGrid in version 2013.3.1114. My SelectMethod is defined in a Business Object. RadGrid throws an exception indicating that it cannot find the method on the page.

I have implemented the OnCallingDataMethods event:

protected void CallingDataMethods(object sender, CallingDataMethodsEventArgs e)
{
e.DataMethodsObject = new BLL();
}

However, RadGrid still attempts to locate the SelectMethod on the page object. Using the OnCallingDataMethods event of RadComboBox works correctly, so I am surprised that it is not working for RadGrid.

Has this been resolved in newer versions of RadGrid? If not, what are my options?

Show only first 50 chars in a specific column

In a RadTreeList I need to show only the first 50 chars in a specific column unless a session variable is valid.

<telerik:TreeListBoundColumn UniqueName="TextM" DataField="TextM" HeaderText="Message" HeaderStyle-Width="400">

<HeaderStyle Width="400px" ></HeaderStyle>

</telerik:TreeListBoundColumn>

Is there a way to achieve such feature?

Thanks for supporting,

AppointmentCreated + DataItem +DataSource +telerik Data Access

Hello

i m fighting with telerik Scheduler and it s the same with all component.

Each Sample :
we miss example with telerik Data Access,
we have a code c# or vb or aspx don't match with the sample.

And each method for the Scheduler are limited.

We want to Find Control with AppointmentCreated (or other if you have)
And get the Datasource to Show in my template control, like textbox or other.

this code doesn't work inside Appoinment Created :

var oAgendaBo = (agenda)e.Appointment.DataItem;

It's not normal, we are always limited, or find a border line idea and we spent a lot time to use some control.
