DataBound ComboBox Problem

Problem:
When you want to use a data bound ComboBox in .NET (C#, VB, etc), you should set a few properties such as DataSource, DisplayMember and ValueMember.
It works fine unless you want to set SelectedValue for the first time. It won’t be set!

Solution:
I found that BindingContext property must be created before initializing SelectedValue:

ComboBox1.BindingContext = new BindingContext();
ComboBox1.DataSource = MyDataSet.DefaultView
ComboBox1.DisplayMember = "Title";
ComboBox1.ValueMember = "Code";
ComboBox1.SelectedValue = 1;
