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,

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.
