How can I change border and background color of the control when any of the validation fails after submit button clicked.
I searched this in google but most of the solution provided in jQuery, but I don't want to use jQuery.

Solution 1

On button Click, try some thing like this

{

if (TextBox1.Text==Null|| TextBox1.Text="")
{
TextBox1.BackColor = System.Drawing.Color.Red;
}

but this code is called when all the validations are valid.

What do you want to do?When if any of the control has error, then you want to display right? The above code will do that if textbox1 dont have any values. You can alter the if conditions according to your logic

but I have putted required field validation control associated with textbox, so when I click the button without any text in the textbox, if condition in not called.

No wat i meant to say is just an example. You have to start it from there. For eg.you dont want textbox1.Text to have integer =6 , then

if (TextBox1.Text.ToString().Contains("6"))
{
TextBox1.BackColor = System.Drawing.Color.Red;
}
