点击asp.net buttom 控件后 跳转到按钮

MaintainScrollPositionOnPostBack 页面的这个属性设为true后没起作用

解决方法：

 

/// <summary> /// 提供一些产生页面脚本的方法 /// </summary> public class ScriptHelper { /// <summary> /// 获取客户端查看控件的脚本 /// </summary> /// <param name= "controlName "> </param> /// <returns> 脚本代码 </returns> public static string GetViewControlScript(string controlName) { //创建客户端函数ViewObj string script = "/n "; script += " <mce:script language=/"javascript/"><!-- /n "; script += "function ViewObj(objName)/n "; script += "{/n "; script += "var obj = document.all.item(objName);/n "; script += "if (obj != null)/n "; script += "{/n "; script += "/tobj.scrollIntoView();/n "; script += "/tobj.focus();/n "; script += "}/n "; script += "}/n "; //创建客户端函数ToDo script += "function ToDo() "; script += "{/n "; script += string.Format("setTimeout(/"ViewObj('{0}')/",500);/n", controlName); script += "}/n "; script += "window.onload = ToDo;/n "; script += " // --></mce:script> /n "; return script; } }

 

 

  protected void btnAdd_Click(object sender, EventArgs e)
        {

 

  this.Page.ClientScript.RegisterStartupScript(this.GetType(), "aa", ScriptHelper.GetViewControlScript  (btnAdd.ClientID)); ; 

}
