Question

I have many asp.net validation controls in my aspx page and I dont want to hard code there error message.

I want to put a variable in C#, set error message there and set text properties of required filed validates. Unfortunately I dont know how to do it.

Please guide me is it possible and how it is possible ?

An ASP.Net Validation Control typically derives from BaseValidator, which has both a Text property as well as a ErrorMessage property.

You can set either of these in your code behind. So given this validator:

<asp:RequiredFieldValidator id="myValidator"
   ControlToValidate="TextBox1"
   Display="Static"
   Width="100%" runat=server />

In your code behind you can do this:

var errorText = "Some Text";
var errorMessage = "It's broken yo!";

myValidator.Text = errorText;
myValidator.ErrorMessage = errorMessage;

The Text property is what shows up directly in the control, and the ErrorMessage is what get’s shown in the ValidationSummary
