asp.net – 删除事件后GridView没有刷新

当我放置一个断点时,我可以看到在LinqDS_Selecting事件之后触发了OnRowDeleting事件.但删除事件后它不再被解雇！这可能是原因吗？我究竟做错了什么？

请有人帮忙.提前谢谢了.

.aspx文件：

<asp:LinqDataSource
    ID="LinqDS"
    runat="server"
    OnSelecting="LinqDS_Selecting">
</asp:LinqDataSource>

<asp:GridView
    DataSourceID = "LinqDS"
    ID = "gv1"
    runat = "server"  
    DataKeyNames = "InstructionId"
    EnableViewState = "false"
    OnRowDataBound = "gv1_RowDataBound" 
    OnRowDeleting = "gv1_RowDeleting" 
    OnRowCommand = "gv1_RowCommand"
    PageSize = "30" >
    <Columns>
        <!-- My colums --->
    </Columns>
</asp:GridView>

.aspx.cs

protected void Page_Load(object sender,EventArgs e)
{

}

protected void LinqDS_Selecting(object sender,LinqDataSourceSelectEventArgs e)
{
    // my linq to sql query
    var query = from  .... .... ;
    e.Result = query;
}

protected void gv1_RowDeleting(object sender,GridViewDeleteEventArgs e)
{
    int instructionId = (int)gv1.DataKeys[e.RowIndex].Value;
    /// my delete logic
    CTX.SubmitChanges();
    gv1.DataBind();
}
