Hi Asoka,

Thanks for your question.

I am not quite sure that I correctly understand what you are trying to achieve. You can use the ShowPopup() method in order to explicitly open the drop down of this control. Take a look at the following code snippet:

private void radButton2_Click(object sender, EventArgs e)
{
    this.radMultiColumnComboBox1.MultiColumnComboBoxElement.ShowPopup();
}

I hope this will help you.

Do not hesitate to get back to me if you need further assistance.

Best wishes,

    End Sub

Hi Asoka,

Thanks for getting back to me with the details.

Please, consider the following code snippet:

Dim item As RadTextBoxItem = TryCast(Me.radMultiColumnComboBox1.MultiColumnComboBoxElement.Children(2).Children(0).Children(0), RadTextBoxItem)

If item IsNot Nothing Then
     AddHandler item.Click, AddressOf OnTextBoxItem_Click
End If

In the OnTextBoxItem_Click event handler you can just open the drop down menu by using the already known method.

I hope this will help you achieve the desired behavior.

Do not hesitate to write back in case of further impediments.
