Change the foreColor of a textbox

Question

I am trying to do something that I believe should be very simple. I am trying to change the forecolor of a textbox depending on what is in the text box. Meaning if the text box has a value of 'UP', I want the forecolor to be RED. If the text box has a value of 'DOWN', I want the forecolor to be BLUE. I am use to programming in SQL (Oracle) over 10 years ago and I would simply state something like: if the textbox.text = "UP" then textbox.forecolor = color.red; ELSIF textbox.text = "DOWN" then textbox.forecolor = color.blue; ELSE textbox.forecolor = color.black;

How does one do it in Visual C#?
Can anyone Help?

Here is a sample assuming 3 things here: 1) The textbox control is named textBox1 2) You want the color to change when textBox1 loses focus 3) Your comparison of the textbox text is case-sensitive private void textBox1_Leave(object sender EventArgs e) { if (textBox1.Text.Equals(DOWN)) textBox1.ForeColor = Color.Blue; else if (textBox1.Text.Equals(UP)) textBox1.ForeColor = Color.Red; else textBox1.ForeColor = Color.Black; }

John Thank you - I see that what I needed were a few of the '(' and ')'. Thank you. I knew it was simple. I can work with that and expand it. Thank you again. Have a Great Day. Craig

I thought I replied to this but did not see it post so I'll try again. John Thank you for your quick replay; however that does not work Hence the question. When I try it as follows: If textbox.text = UP I get cannot implicitly convert type 'string' to 'bool'. When I put a == I get that only certain expressions can be used as a statement. I have it where the text box is populated when I enter the menustrip (Navigation menu) and that works great. I even have the text box changing colors when I enter the textbox. This is just something that would be kind of neat to do - changing the color based on the value of the text. I can imagine that things would neat to change depending on certain values entered by the user. I know that this can not be THAT difficult I just don't know how to do it yet. Can anyone help? Or Will anyone help me?

That is how you do it... set the ForeColor property of the TextBox control.
