This behavior strongly depends on the exact type of "TextBox". There are different types under the same name, so you need to give us full name of it. Generally, you always need to tag the UI library you use, when the question is about UI. Please, exact type.

You could just add this to the class

protected override void OnPreviewKeyDown(KeyEventArgs e)
{
  e.Handled = e.Key == Key.Space;
  base.OnPreviewKeyDown(e);
}

Hope, this helps.

Thanks,

Check char code and omit it :)

I tried like this it's working fine.

C#

if (txtDeathFirstName.Text.Length == 0 && e.KeyChar == ' ')
           {
               e.Handled = true;
           }
           else
           {
               e.Handled = false;
           }
