CustomValidator issues with MultiView-control : The Official Microsoft ASP.NET Forums

if you want to validate customvalidator which is present in "anothor view" (Not activew view), then before validating you need to set activeview index as that "anothor view" and then validate page.

if page is valid then redirect it to another page else do nothing.

To prevent next or previous page when page.isvalid = false you can use IPostBackEventHandler concept.

Anyone know how to prevent next or previous page when page.isvalid = false?

Assume that previous page and next page are controlled by a Button(Or similar controls ) control. You can check the page.isvalid value to decide the control is enabled or disabled:

if(!page.isvalid)

{ nextButton.Enabled =false;}

you can do it in javascript too...you can check for Page_ClientValidate(), it returns flase if validations fail....use that same like "return Page_ClientValidate()" in onclientclick for a button...

Try stepping through the Views using the following example.

protected void MoveNext_Click(object sender, System.EventArgs e)
{
    if (mvForm.ActiveViewIndex > -1 & mvForm.ActiveViewIndex < 2)
    {
        if (Page.IsValid)
        {
            // Validate fields
            switch (mvForm.GetActiveView().ID.ToString())
            {
                case "vStep1":
                    if (tbFirstName.Text.Trim().Length == 0 || tbLastName.Text.Trim().Length == 0)
                    {
                        // Handle error
                    }
                    else
                    {
                        // Move to next step
                        mvForm.ActiveViewIndex += 1;
                    }
                    break;
                case "vStep2":
                    if (tbStreet.Text.Trim().Length == 0 || tbCity.Text.Trim().Length == 0 || tbZipCode.Text.Trim().Length == 0)
                    {
                        // Handle error
                    }
                    else
                    {
                        // Move to next step
                        mvForm.ActiveViewIndex += 1;
                    }
                    break;
                case "vStep3":
                    if (tbComments.Text.Trim().Length == 0)
                    {
                        // Handle error
                    }
                    else
                    {
                        // Move to next step
                        mvForm.ActiveViewIndex += 1;
                    }
                    break;
            }
        }
    }
    else
    {
        // Handle error
    }
}
