Hello Telerik.
I have a question RadCoboBox's "SelectText" function.
It can select part of text through selected length.
I tried use this function but it doesn't work.
So i have tried many test, finally getting result.
If i want to use SeelectText function , i should to set some properpties.
EnableTextSelection="true" EnableLoadOnDemand="true".
that properies are set true, selectText was worked.
Is it bug or planned scenario?
I attached sample code please check this.

Hi Shunman,
because at the moment there are other events which are fired immediately after you focus the combo.
I hope this helps.

Try to call this in RadComboBox1_DropDownOpened event:
function RadComboBox1_DropDownOpened(sender,args){ sender.selectText(0, 2);}<telerik:RadComboBox ID="RadComboBox1" runat="server" Width="350" EnableTextSelection="true" EnableLoadOnDemand="true" TabIndex="3" OnClientFocus="RadComboBox1_Focus" OnClientDropDownOpened="RadComboBox1_DropDownOpened"> <Items> <telerik:RadComboBoxItem Text="1111111" Selected="false" /> <telerik:RadComboBoxItem Text="2222222" /> <telerik:RadComboBoxItem Text="3333333" /> <telerik:RadComboBoxItem Text="4444444" /> </Items></telerik:RadComboBox>because at the moment there are other events which are fired immediately after you focus the combo.
I hope this helps.
