我有一段代码用于搜索records.And，我添加了页面索引，但是它不会出现properly.When单击search按钮，它显示了更多的记录，此时页面索引不起作用。它正在调用第一个网格，然后单击搜索button..How，我可以更改我的代码，请帮助我……

试试这个..。

    private void grid()
   {
      if(!string.IsNullOrEmpty(yourSearchTextBox.Text)
      {
      // Then call search method. Make sure you bind the Grid in that method.
      }
      else
      {
      // Normally Bind the Grid as you are already doing in this method.
      }
   }

您必须检查网格()方法中是否有搜索文本，比如.
