Hi

I have created the validation summary control dynamically(see code section)


even if validation fails I am not able to see the validation
ValidationSummary oValidationSummary = new ValidationSummary();
                    oValidationSummary.ID = "val";
                    oValidationSummary.DisplayMode = ValidationSummaryDisplayMode.BulletList;
                    oValidationSummary.EnableClientScript = true;
                    oValidationSummary.ShowSummary = true;
                    
 
                    CustomValidator oCustomValidator = new CustomValidator();
                    oCustomValidator.ID = "cvName";
                    oCustomValidator.Visible = true;
                    oCustomValidator.ControlToValidate = ID;
                    oCustomValidator.Enabled = true;
                    oCustomValidator.ValidateEmptyText = true;
                    oCustomValidator.ErrorMessage = MTBErrorMessage;
 
                    oCustomValidator.ServerValidate += new ServerValidateEventHandler(oCustomValidator_ServerValidate);
 
void oCustomValidator_ServerValidate(object source, ServerValidateEventArgs args)
        {
            Validation oValidation = new Validation();
            bool status = true;
            status = oValidation.IsValid(MTBValidationType, Text);
 
            args.IsValid = status;
}

Dynamically created controls should be added from within the Page_Init event even on postbacks, otherwise there expected events would not fire.
Let me get back to you with a link to a recent discussion on EE on about the same matter.

If you are asking about WebUserControl, then yeah surely you can add. And if you are Custom Web Server Controls, I think it should allow you to have this.

I have implemented in that way(code section)

but the debugging control is not going on Page init
private void Page_Init(object sender, EventArgs e)
        {
            if (MTBErrorMessageControlType == MTBErrorMessageControl.VALIDATIONSUMMARY)
            {
                ValidationSummary oValidationSummary = new ValidationSummary();
                oValidationSummary.ID = "val";
                oValidationSummary.DisplayMode = ValidationSummaryDisplayMode.BulletList;
                oValidationSummary.EnableClientScript = true;
                oValidationSummary.ShowSummary = true;
 
 
                CustomValidator oCustomValidator = new CustomValidator();
                oCustomValidator.ID = "cvName";
                oCustomValidator.Visible = true;
                oCustomValidator.ControlToValidate = ID;
                oCustomValidator.Enabled = true;
                oCustomValidator.ValidateEmptyText = true;
                oCustomValidator.ErrorMessage = MTBErrorMessage;
                oCustomValidator.ServerValidate += new ServerValidateEventHandler(oCustomValidator_ServerValidate);
            }
        }
        void oCustomValidator_ServerValidate(object source, ServerValidateEventArgs args)
        {
            Validation oValidation = new Validation();
            bool status = true;
            status = oValidation.IsValid(MTBValidationType, Text);
 
 
            args.IsValid = status;
 
        }

Try putting breakpoints on the Page_Init code. If it does not solve, go to Tools > Options > Debugging and check if a certain setting is prohibiting debugger to break in user/custom control.
One more thought, if you have placed this code in a separate DLL and only referencing this DLL in your active project withou Debug Symbols, you may have the problem with debugger.

I just tested at my machine in VS2008 that the Page_Init on a WebUserControl is being debugged by the Debugger. Please look into the settings of VS2008 Debugger.
