    What's the best way to realize a two way binding between two RadComboBox's?

    I have a user control wit only a RadComboBox that get filled with company names and companyID's I have two fill() methods. Both sets the companyId as value and one with the company name as text and the other the companyID as text.
    I use two user controls in a Edit-FormTemplate van the RadGrid. setting them in ItemCreate event - One shoving the company name and the other shoving the companyID,. They are both set to the same SelectedIndexChanged evnt.

    In this SelectedIndexChanged I want to set the Selected value of both when the event is fired. But how do find the Usercontrols?

    I tried various code snippert but I can'get it to work, so as this:
    var temp = (sender as RadComboBox).NamingContainer.NamingContainer;
    DealerComboBox combo = (DealerComboBox)temp.FindControl("DealerComboBoxCodeCode");

    Please help

    Hello Anders,

    I would suggest you to initially find the UserControl and than use the FindControl again, to find the RadComboBox, nested in the UserControl. I have prepared a sample project for you, demonstrating the above suggested implementation. Please find it attached.

    Note : dll files are removed from the attachment.
