How to display empty string in editor controls when databound value is null?

Platform: WinForms |
Control: TextBoxExt |
Published Date: April 30, 2011 |

We can display empty string when databound value is null. For this we need to bind the editor controls ( like IntegerTextBox, DoubleTextBox, etc.,) to BindableValue property and also we need to set UseNullString to true and NullString property to empty string .

Please find the code snippet below that illustrates the same.


this.integerTextBox1.NullString = "";

this.integerTextBox1.UseNullString = true;

this.integerTextBox1.DataBindings.Add("BindableValue", boundView, "IntegerField");


Me.integerTextBox1.NullString = ""

Me.integerTextBox1.UseNullString = True

Me.integerTextBox1.DataBindings.Add("BindableValue", boundView, "IntegerField")

Here is the sample that demonstrates this. Sample
