Need help on combo box and textbox event

[todoink]

Hello,

I need a code. This is only a simple problem. I have 1 combo box and 1 textbox. The combo box has the ffg. items : 1, 2 and 3. What I want to happen is when I select an item on the combo box, that item will appear on the textbox. For example I've choose 1 on the combo box, then a number 1 will be shown on the textbox. Same thing goes with 2 and 3. Thanks a lot.

TextBox1.Text = ComboBox1.SelectedItem.ToString

TextBox1.Text = ComboBox1.SelectedItem.ToString

That will work as long as the ComboBox contains simple values, like strings or numbers. If you've bound data to the ComboBox then each item is a DataRowView so that will not be useful. The "proper" way to do this so it will work in all situations would be:

myTextBox.Text = myComboBox.GetItemText(myComboBox.SelectedItem)

or just:

myTextBox.Text = myComboBox.Text

Whatever the case, you have to handle the SelectedIndexChanged or SelectionChangeCommitted event of the ComboBox.

If they were data bound controls, you would bind them through the same binding context, and all would be simple
