Hi Neils, In your scenario the text box font color should change when the text box loses its focus ie: once the data entry is complete and the user leaves the control . You can make use of the Leave event handler for this implementation . private void textBox1_Leave(object sender, EventArgs e) { if (textBox1.Text.Equals(" emergency ")) textBox1.ForeColor = Color.Red; else if (textBox1.Text.Equals("high")) textBox1.ForeColor = Color.Blue; } More reference : https://msdn.microsoft.com/en-us/library/system.windows.forms.control.leave(v=vs.110).aspx Thanks, Priyan If you found this useful Please mark this as Answer

Hi, You can use textbox change method.Inside the method wrote the following code.. // If your value is static then you can use this code otherwise modify this.... protected void TextBox1_TextChanged(object sender, System.EventArgs e) { if(TextBox1.Text.ToLower() == " emergency ") { TextBox1.ForeColor = Color.Red; } }
