asp.net OnSelectedIndexChanged未在网格视图中触发

网格视图代码：

<asp:GridView ID="gvVessel" runat="server" AutoGenerateColumns="false" GridLines="None"
     EmptyDataText="No Vessels found." OnRowCommand="gvVessel_RowCommand"      
     OnSelectedIndexChanged="gvVessel_SelectedIndexChanged" DataKeyNames="VesselID" >
<asp:/GridView>

代码隐藏：

protected void gvVessel_SelectedIndexChanged(object sender, EventArgs e)
{
    int index = Convert.ToInt16(gvVessel.SelectedDataKey.Value);
    Cache["index"] = index;

    Response.Redirect("VesselDraft.aspx");
}

为什么事件未激发？

gridview SelectedIndexChanged Event is not firing.I am using asp.net 4.0 .By the way rowdatabound event is firing perfectly
如果您只是单击GridView中的行，则不会触发事件。您必须在要单击的行中有某种按钮，它将触发RowCommand事件和SelectedIndexChanged事件（当然，如果您单击的行尚未被选中）。这与Windows窗体DataGridView =不完全一样。
触发事件的最简单方法是将此属性添加到GridView标记中：

AutoGenerateSelectButton="True"

这将创建一个“Select”LinkButton，当您单击它时，它将在代码隐藏中激发Gridview1_SelectedIndexChanged2事件。

**EDIT：**为了澄清，您需要在此处添加该属性：

<asp:GridView ID="GridView1" runat="server" GridLines="None" 
  Width="930px" CellPadding="4" ForeColor="#333333"  
  onselectedindexchanged="GridView1_SelectedIndexChanged2"
  AutoGenerateSelectButton="True" >
