Multicolumn Combo Box

[Scott Griswold]

When a Multicolumn Combo Box is bound to a data source the combo shows the first item in the list rather then a blank. I have tried several ways to change this behavior, but have not been successful. Is there a way to programmatically blank out the combo box so that the user has to make a selection?

Hi Scott,

You can programmatically blank out the combo box by setting the text property to null after setting the data source.

Below is the code snippet:

this.multiColumnComboBox1.DataSource=mt;        
this.multiColumnComboBox1.DisplayMember="ProductID";
this.multiColumnComboBox1.ValueMember = "ProductName";
this.multiColumnComboBox1.Text = null; 

Please refer the sample and let us know if this helps.
