添加OnClick事件asp.net网格视图 [英] Add OnClick event for asp.net grid view

问题描述

我在RowDataBound事件动态地添加新的事件即Gridview_Onclick事件。但是，当我试图处理在服务器端code这种情况下，我可以code该事件。这是code我的网格视图。

I have added new event i.e Gridview_Onclick event dynamically in RowDatabound event. But when I try to handle that event in the server side code, I can code for that event. This is the code for my grid view.

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="PopUp.ascx.cs" Inherits="PopUp" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

<table class="style1">
<tr>
    <td>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            CellPadding="4" ForeColor="#333333" GridLines="None" 
            onrowdatabound="GridView1_RowDataBound">
            <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
            <Columns>
                <asp:BoundField DataField="DeptId" HeaderText="ID"/>
                <asp:BoundField DataField="Name" HeaderText="Name"/>
                <asp:BoundField DataField="HeadName" HeaderText="HOD"/>
                <asp:BoundField DataField="HeadEmail" HeaderText="Email ID"/>
            </Columns>
            <EditRowStyle BackColor="#999999" />
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
            <SortedAscendingCellStyle BackColor="#E9E7E2" />
            <SortedAscendingHeaderStyle BackColor="#506C8C" />
            <SortedDescendingCellStyle BackColor="#FFFDF8" />
            <SortedDescendingHeaderStyle BackColor="#6F8DAE" />
        </asp:GridView>
        <asp:Button ID="btnTest" runat="server" style="display:none" />
    </td>
</tr> 
</table>

这是在code我ascs.cs页

This is the code for my ascs.cs page

protected void Page_Load(object sender, EventArgs e)
{
    oCommand.CommandText = "select * from Department";
    oCommand.Connection = oConnection;
    oAdapter.SelectCommand = oCommand;
    DataTable dt = new DataTable();
    oAdapter.Fill(dt);
    GridView1.DataSource = dt;
    GridView1.DataBind();
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Attributes["OnClick"] = Page.ClientScript.GetPostBackClientHyperlink(e.Row, string.Empty);
}
protected void GridView1_OnClick(object sender, GridViewRowEventArgs e)
{
    _ID = "10";
    _Name = "abc";
    _HOD = "abc";
    _Email = "abc";
}

网格视图中打开modelpopupextender所以当我点击任何地方电网，它得到关闭，这就不是我的情况下删除动态添加事件。在短路事件中加入，但不能在code处理。 请指导我怎样才能在编码赶上这个活动？

The grid view opens in modelpopupextender so when I click anywhere in grid, its getting closed which is not the case of I remove the event that is added dynamically. In short the event is added but can not be handled in code. Please guide me how can I catch this event in coding??

推荐答案

您需要做以下为您code的变化： 1）

You need to do following changes at your code: 1)

 e.Row.Attributes["OnClick"] = Page.ClientScript.GetPostBackClientHyperlink(**btnTest**, string.Empty);

2）

 protected void GridView1_OnClick(object sender, **EventArgs** e)

3）＆LT; ASP：按钮的ID =为btnTest=服务器风格=显示：无**的OnClick =GridView1_OnClick** /＆GT;

为什么？

原因是GridViewRow没有实现IPostBackEventHandler，因此没有按消防回发事件。但按钮即可。在这种情况下，为btnTest是虚拟按键事件射击。

The reason is GridViewRow doesn't implement IPostBackEventHandler, therefore doesn''t fire postback events. But button can. At this case btnTest it is dummy button for event firing.
