I have one TextBox. I want to make textbox readonly property true or false during an event.

I set the TextBox readonly property as true by the following code:

   txtNoOff.Attributes.Add("readonly", "readonly");

But how to make textbox readonly property false? I have tried like below:

   txtNoOff.Attributes.Add("readonly", "false");

But it does not work. How to achieve this? I need all ur suggestions please.

Just remove the readonly attribute: txtNoOff.Attributes.Remove("readonly");
