How to change text box background text?

Hi,

This is the solution,

you have to change the textbox fore color in the form load

textBox1.ForeColor = Color.Black;

and you have to write this code in the text box mouse click event

private void textBox1_MouseClick(object sender, MouseEventArgs e)
{
    textBox1.Text = "";
    textBox1.ForeColor = Color.Black;
}

Try this :)

Thanks.

You can do it using the onFocus and lostFocus event.

When the TextBox gets the focus, you can clean the textbox, and when it lost, you can paint if needed.

Try something like this:

private void window_Loaded(object sender, RoutedEventArgs e)
{
textbox1.Text = "Enter Name...";
}

private void textBox1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
textbox1.Text = "";
}

then add your fore color bits and bobs and sorted!

Hope this helps

Hi
first Go to the textbox's properties and set Text as:

Enter your Name:

private void Form1_Load(object sender, EventArgs e)
        {
textBox1.foreColor = Color.LightGray;
}

        private void textBox1_MouseClick(object sender, MouseEventArgs e)
        {
if(textBox1.Text == "Enter your Name:")
{
            textBox1.Text = "";
            textBox1.ForeColor = Color.Black;
}
        }

Hope this will help you

thanx.

Change color in the handler of the event TextChanged. Further details depends on the UI library you want to use. You did not specify it; see my comment to the question.

There is more to consider when creating such a scenario... an aspect you may not have considered yet would be validation. If you will be saving the input somewhere, do you plan to see if the user entered a name? Are you going to simply check for the prompt "Enter your name:" and dismiss that input?

The enter, leave, lostfocus etc events are fine to control what the textbox says and in what foreground color... but to make it really effective, especially if you're going to have many boxes like this, you should create your own control that handles the prompting and provides a validation method to the UI.

Just my .02 on the subject... as far as code, others have given you basic code to toggle text and forecolor... the rest is best left to existing tutorials on custom controls.

Best of luck!

Found one of the aritcles...
