gridview选择索引更改事件未触发 [英] gridview selected index changed event not firing

问题描述

我在aspx页面中有一个gridview。我已经通过javascript进行了行选择。当我使用母版页时，selectedindexchanged事件无效。否则它工作正常。对此有什么解决方案吗？



请看我背后的代码

I have a gridview in an aspx page. I have made it row selection by javascript. The selectedindexchanged event is not working when i am using master page. Otherwise it works fine. Is there any solution for this?

Please see my code behind

public partial class WebForm2 : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
   {
       if (!IsPostBack)
       {
           GridView1.DataSource = Enumerable.Range(1, 10).Select(a => new
           {
               ID = a,
               FirstName = String.Format("First Name {0}", a),
               LastName = String.Format("Last Name {0}", a)
           });
           GridView1.DataBind();
       }
   }
   protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
   {
       lblSelectedRow.Text = String.Format("You selected row {0} with {1} {2}",
                                               GridView1.SelectedIndex + 1,
                                               GridView1.SelectedRow.Cells[0].Text,
                                               GridView1.SelectedRow.Cells[1].Text);
   }
   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
   {
       if (e.Row.RowType == DataControlRowType.DataRow)
       {
           //add css to GridViewrow based on rowState
           e.Row.CssClass = e.Row.RowState.ToString();
           //Add onclick attribute to select row.
           e.Row.Attributes.Add("onclick",
           String.Format("javascript:__doPostBack('GridView1','Select${0}')",  e.Row.RowIndex));
       }
   }
