[Solved] How to get RadCombobox PostbackUrl to open in new window

[William Corry]

I have a form where the user selects a value on a Radcombobox that has a PostbackUrl that is a different webpage.  The new webpage uses the information on the previouspage variable as the source of parameters for its Sqlserverdata sources.  The issue I'm having is that the process of opening the new webpage destroys the old one.  I don't see a target property on the Radcombobox.  Is there a way to get the webpage specified by the PostbackUrl to open as a new webpage?

Thanks,

Hi William Corry,

Unfortunately this is not possible. I may suggest a workaround though - to use the window.open JavaScript method and open a new window passing the required data as query string parameters. You can use the OnClientSelectedIndexChanged event of the combobox. Here is a quick example:

<script type="text/javascript">
function selectedIndexChanged (sender, args)
{
     window.open("Page.aspx?selectedValue=" + sender.get_value(), "_blank");
}
</script>
<telerik:RadComboBox runat="server" ID="RadComboBox1" OnClientSelectedIndexChanged="selectedIndexChanged">
   <Items>
           <telerik:RadComboBoxItem Text="One" />
           <telerik:RadComboBoxItem Text="Two" />
           <telerik:RadComboBoxItem Text="Three" />
   </Items>
</telerik:RadComboBox>
