I have tried setting it in the code and also in the markup but when the Next Button is clicked, the page is validated, I want to prevnt this from happening and control when validation should occur and when not. Any suggestions or code samples would be appreciated

推荐答案

要做到这将是从的WizardStep 中验证删除所有验证程序控件的最简单方法被跳过。

The easiest way to do this would be to remove all validator controls from the WizardStep in which validation is to be skipped.

不过，如果你需要高级功能，您将需要设置一个/ previous按钮的的CausesValidation 属性在 StepNavigationTemplate 手动。 ASP.NET的向导控件不公开，使您可以直接访问NavigationTemplates控件的属性，也没有公开任何属性来访问NavigationTemplate。因此，我们需要依靠的FindControl 方法做所有的搜索。

However, if you need advanced functionality, you will need to set the CausesValidation property of the Next/Previous buttons in your StepNavigationTemplate manually. The ASP.NET Wizard control does not expose properties that let you access the controls in the NavigationTemplates directly, nor does it expose any properties to access the NavigationTemplate. So, we need to rely on the FindControl method to do all the searching.

一个得心应手的资料片，我发现虽然研究这个问题是，在运行时， StepNavigationTemplate 是所谓的内部ASP.NET类型的 StepNavigationTemplateContainer 并有一个ID为StepNavigationTemplateContainerID。这使我能够找到 StepNavigationTemplate ，因此，下一步按钮。

A handy piece of information that I found while researching this problem was that at runtime the StepNavigationTemplate is of an internal ASP.NET type called StepNavigationTemplateContainer and has an ID "StepNavigationTemplateContainerID". This enabled me to locate the StepNavigationTemplate and therefore, the Next Button.

code如下：

---

protected void Wizard1_ActiveStepChanged(object sender, EventArgs e)
{
  int step = Wizard1.ActiveStepIndex;

  // Disable validation for Step 2. (index is zero-based)
  if (step == 1)
  {
    ToggleValidation(false);
  }
  else  // Enable validation for subsequent steps.
  {  
    ToggleValidation(true);
  }
}

private void ToggleValidation(bool flag)
{
  WebControl stepNavTemplate = this.Wizard1.FindControl("StepNavigationTemplateContainerID") as WebControl;
  if (stepNavTemplate != null)
  {
    Button b = stepNavTemplate.FindControl("StepNextButton") as Button;
    if (b != null)
    {
      b.CausesValidation = flag;
    }
  }
}
