TabIndex should work. The focus will reset to starting TabIndex if any postback occurs. In that case, you need to set the focus to the control from codebehind. If you need code to set focus on control from code behind, please let me know :)

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.

C#

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

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

C#

/// <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;
    }

Thanks for all of your valuable comments..
