Hi
I have three TextBoxes in C# Windows Application and one Button.
If user clicks a Button then I check if any TextBox is empty, then I use
MessageBox.Show("You cannot use a blank TextBox") and after automatic set focus in blank TextBox
I do this but I do not set focus in blank TextBox. So what do I need to do?
Please help me

Thanks in advance

Do you really need to show a messagebox.
Is the purpose of messagebox is just to convey the error/warning, if Yes then I think you can use errorprovider control.
