Validation Controls

18y1.8k.NET

Can we create validation controls dynamically at runtime? I had a textbox and a button control on my page and I created a custom validator control in the Page_Load event handler for the textbox to accept M and F only as gender values. But when I run my script, its complaining about the runat=server tag. Any ideas????

That's working for sure. Thanks for the idea. I am getting dumb these days.

Prasanna,

I am not sure whether this approach will help you. Instead of creating validation control on run-time, you may create that control on design time with Enabled="false". It will not work by default. When you click the checkbox, make that validation control is Enable, when its checked. Otherwise make that disable. See the following example:

protected void chkTest_CheckedChanged(object sender, EventArgs e)
{
reqTest.Enabled = chkTest.Checked;
}

When you click the button, you can see how it works.

There is a Details checkbox in the same page. So if the checkbox is ticked I want to validate the textbox. In other case, I want to process the page without validation. Thats why I am creating the validation control at runtime.

It is possible. Can you give us little more detail about your requiremnt. Why are you expecting to create the validation control on run-time since you are not creating the textbox on run-time? Also give us your code snippet.
