setting validator control's text from C# variable in aspx code?

Question

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

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

@user576510 - I'm not completely sure I understand what you want at this point, but I've updated the answer to show how you could initialize the control properties from a variable.
