I want to check on the server side if the user has selected an item from the drop-down list, or if he has entered custom text. With a RadComboBox, the SelectedIndex property is -1 for custom text, and 0, 1, 2, ... for a drop-down item. But the MultiLineComboBox does not have such a property. How else can I check on the server side if the user has entered custom text?

Steps:
2. Enter "ha" select some records
3. Click out of the dropdown to close it
4. Textbox keeps "ha" but the message below reads that You have selected Thomas Hardy whose ID is AROUT. They are a Sales Representative at Around the Horn however, nothing has been selected.
Is it expected ?
If it's a bug and having a long cycle to fixing bugs could you recommend any workaround?

And getting compile time error -

Is there any way to restrict the user from entering custom text into a databound multicolmncombobox. Forcing them to select an existing item. A dropdown list is not usable as it is bound to a table which has 5000 records. Some filtering based on a couple of fields is required.

I noticed in the RadMultiColumnComboBox that the cursor appears to be a text-insertion/editing cursor instead of an arrow. I'm using this to allow the user to select an item so the text cursor is unintuitive. Is there a way to set the style of the mouse cursor on this control?
<telerik:RadMultiColumnComboBox runat="server" ID="radMultiComboPhrases" DropDownWidth="200px" Height="400px" AutoPostBack="true" Placeholder="Select a phrase..." DataTextField="sBrief" DataValueField="sPhrase" RenderMode="Mobile">
<ColumnsCollection>
<telerik:MultiColumnComboBoxColumn Field="sBrief" Title="Brief Desc." Width="200px"></telerik:MultiColumnComboBoxColumn>
<telerik:MultiColumnComboBoxColumn Field="sPhrase" Title="Phrase" Width="200px"></telerik:MultiColumnComboBoxColumn>
</ColumnsCollection>
</telerik:RadMultiColumnComboBox>

Hi,
I have the following snippet in my ASP.NET
<TELERIK:RADMULTICOLUMNCOMBOBOX ID="RadMultiColumnComboBoxSearch" runat="server" Filter="startsWith" FilterFields="DrawingName, Description"
Height="800" AllowPaging="true" EnableServerFiltering="true" MinLength="3" PageSize="60" DataTextField="DrawingName" DataValueField="DrawingID">
<COLUMNSCOLLECTION>
<TELERIK:MULTICOLUMNCOMBOBOXCOLUMN Field="DrawingID" Title="ID" />
<TELERIK:MULTICOLUMNCOMBOBOXCOLUMN Field="DrawingName" Title="Name" />
<TELERIK:MULTICOLUMNCOMBOBOXCOLUMN Field="Description" Title="Description" />
</COLUMNSCOLLECTION>
<WEBSERVICESETTINGS ServiceType="XML" Select-DataType="JSON" Select-Url="Default.aspx/GetDrawingsSuggestion" Select-RequestType="Post" />
</TELERIK:RADMULTICOLUMNCOMBOBOX>
[WebMethod()]
public static string GetDrawingsSuggestion(string filter)
{
string filterText = HttpUtility.UrlDecode(filter);
using (HEN_INTRANET_ProductionEntities dc = new HEN_INTRANET_ProductionEntities())
{
var q = from d in dc.tbl_ENECR_Drawings
where (d.DrawingFlag == 1 | d.DrawingFlag == 2) && d.DrawingTypeID == 1
select new
{
DrawingID = d.DrawingID,
DrawingName = d.DrawingName,
Description = d.Description,
};
var drawingsList = q.ToList();
return Newtonsoft.Json.JsonConvert.SerializeObject(drawingsList);
}
}
Can I use a page method service to get the data I need from the server?
Looking in Fiddler the call to the GetDrawingsSuggestion method occurs, but it returns the page contents. It does not execute the method. It just returns the rendered page.

Hello, I am having problems running RadClientDataSource (data is loaded into RadMultiColumnComboBox) and KendoGrid on the same page. I get strange Ajax and Kendo errors in console about stuff being undefined. Are there any known incompatibilities between some Telerik UI controls and Kendo UI widgets? Are there controls that prefer external jQuery over internal one bundled in Telerik UI?

On the grouping demo page, I'm wondering if there's a bug.
When looking at the contents of the grouped combobox list, the grouping label of Argentina is shown as a column header instead of the black text to the right side.
