使用选项卡时处理控制焦点 [英] Handle control focus while use tab

问题描述

嗨朋友们，



如何在点击标签时处理控制焦点。在我的表单中，当我点击一个标签时，有时焦点会转到母版页标识。我有接下来的行中的文本框控件列表。



我在每个控件中都使用了TabIndex属性。但是，没用。请建议我任何解决方案。非常感谢您的帮助。谢谢你提前。

嗨朋友们，



我已经解决了上述问题。在那种情况下，在某些情况下会发生回发。这是我的TabIndex属性为什么不起作用的唯一原因？现在，我的TabIndex工作正常。另外，我在回发发生后添加了一些控制焦点。以下代码是我在聚焦后使用的。

Hi friends ,

I have resolved myself in above question. I that case , the postback is occurred in some cases. This is the only reason my TabIndex property why was not work ? now , My TabIndex working properly. Additionally , I am add some control focus after postback was occurred. The following code was i am used after focusing.

if (IsPostBack)
      {
          Control ctrl = GetControlThatCausedPostBack(this.Page);

          if (ctrl != null)
              ctrl.Focus();
      }

/// <summary>
    /// Retrieves the control that caused the postback.
    /// </summary>
    /// <param name="page"></param>
    /// <returns></returns>
    private Control GetControlThatCausedPostBack(Page page)
    {
        //initialize a control and set it to null
        Control ctrl = null;

        //get the event target name and find the control
        string ctrlName = page.Request.Params.Get("__EVENTTARGET");
        if (!String.IsNullOrEmpty(ctrlName))
            ctrl = page.FindControl(ctrlName);

        //return the control to the calling method
        return ctrl;
    }

感谢您的所有宝贵意见..
