    I am having an issue with the drop down portion of the combo box staying dropped after a selection is made and the selectedIndexChange event is fired.  
    I am using the selectedIndexChanged event to pop up a input box asking the user to input a qty.  The drop down is not hiding when a selection is made.  It stays up in the way of the input box until the input box is completed. 

    Here is my code. 

    'Code for filing combobox.

    drpModelNumber.AutoCompleteMode = AutoCompleteMode.Suggest

    drpModelNumber.DataSource = oUnitsDT

    drpModelNumber.DisplayMember =


    'code for selected index

    Private Sub drpModelNumber_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles drpModelNumber.SelectedIndexChanged


    "Please Enter the Quantity", "Quantity", "", , )

    End Sub

    Any suggestions?

    Hi Mike,

    Thank you for writing.

    We're sorry for the inconvenience. This is a known issue which has already been investigated. It concerns the internal system mechanism of displaying message boxes and other windows as the drop-down window. For the time being, we haven't found a complete solution and currently the drop-down windows remain visible until the message box is hidden.

    Fortunately, there is a simple workaround:


    You should add this line before showing the message box (or in your case - input box).

    I hope this helps. If you have any additional questions, please don't hesitate to write us again.

    Best wishes,
    the Telerik team
