ToolTip, not ToolTip ? RRS feed

  • Question

  • Hello,

    Very often when you browse the web you run into a textBox with something that appears like a ToolTip inside. Frequently this text inside is kind of dimmed, you put a cursor in the window and the text disappears. It may say something line: "Your email," or have already your zip code as a prompt.

    I want to reproduce it in my coding but both tooltips don't give similar effect. I also checked all properties for the TextBox in C# ToolBox and could not find anything. It can probably reproduced programmatically but I wonder about a special property.

    Can it be done in MSVS?

    Thanks, - MyCatAlex

  • In Win32 Edit controls, it is done with EM_SETCUEBANNER

  • There is nothing in the C# language that will do that, you need to use a GUI such as WPF or Windows Forms to do that. So this question should not be in the C# language forum.

    You can probably draw the text using graphics, as in How to: Draw Text on a Windows Form. However that sample is misleading; see the part that says "you should override the OnPaint method". That makes it more complicated. See Graphics and Drawing in Windows Forms for a description of graphics in Windows; I am sure you don't want to have to read all of that but it is relevant to most all uses of graphics in Windows.

    If you are using WPF and not Windows Forms then you should have said that.

  • Hi MyCatAlex,

    Thank you for posting here.

    For your question, here is a simple code of tooltip for your reference.

      private void TextBox1_MouseMove(object sender, MouseEventArgs e)
                TextBox TB = (TextBox)sender;
                int VisibleTime = 1000;  //in milliseconds
                ToolTip tt = new ToolTip();
                tt.Show("Your email", TB, 0, 0, VisibleTime);
                textBox1.Visible = false;

    Best Regards,
