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

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;

}

}

hi niels,

Kindly try this :-

IF (value =='Emergency')

{

Textbox1.BackColor = System.Drawing.ColorTranslator.FromHtml("#F2F0E1"); //red color code

}

else

{

Textbox1.BackColor = System.Drawing.ColorTranslator.FromHtml("#F2F0E1"); // green color code

}
