GridView等控件中嵌套Button处理数据的方式

方法一：是在模板中直接嵌套，指定其后台处理方法，在后台方法中通过寻找其parent 处理相关数据。

<asp:GridView ID="grvwList" CssClass ="GridViewStyle"  runat="server" AutoGenerateColumns="False" AllowPaging="True" OnRowDataBound="grvwList_RowDataBound" OnPageIndexChanging="grvwList_PageIndexChanging">
                        <Columns>
                            
                            <asp:BoundField DataField="fld_Name" HeaderText="服务名称">
                                <ItemStyle Width="150px" />
                            </asp:BoundField>
                            <asp:BoundField DataField="fld_PointPerUnit" HeaderText="计费点数" >
                                <ItemStyle Width="100px" />
                            </asp:BoundField>
                            <asp:BoundField DataField="fld_Cycle" HeaderText="计费周期" >
                                <ItemStyle Width="100px" />
                            </asp:BoundField>
                            <asp:BoundField DataField="fld_Unit" HeaderText="计费单位" >
                                <ItemStyle Width="100px" />
                            </asp:BoundField>
                            <asp:BoundField DataField="fld_Remark" HeaderText="备注" >
                                <ItemStyle Width="200px" />
                            </asp:BoundField>
                            <asp:TemplateField HeaderText="订制服务">
                            <ItemTemplate><asp:CheckBox ID="cBoxCheck" runat="server" AutoPostBack="true"  OnCheckedChanged="cBoxCheckHandler" /></ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField Visible="False">
                            <ItemTemplate>
                            <asp:Label ID="labHidden" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "existid")%>'></asp:Label>
                            </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField>
                            <ItemTemplate>
                                &nbsp;<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">查看详情</asp:LinkButton>
                            </ItemTemplate>
                            </asp:TemplateField>
                        </Columns>
                                   <HeaderStyle CssClass="GridViewHeaderStyle " />
            <RowStyle Height="20px" CssClass="GridViewRowStyle " />
           <%-- <SelectedRowStyle CssClass="GridViewSelectedRowStyle " />--%>
            <AlternatingRowStyle CssClass="GridViewAlternatingRowStyle " />
            <FooterStyle CssClass="GridViewFooterStyle " />
            <PagerStyle CssClass="GridViewPagerStyle " />
                    </asp:GridView>

后台代码：

protected void cBoxCheckHandler(object sender, EventArgs e)
    {
        CheckBox check = (CheckBox)sender;
        GridViewRow gRow = check.Parent.Parent as GridViewRow;
        SqlConnection con = new SqlConnection(ConnString.GetCrunodeConnStr());
        SqlParameter[] _para ={
            new SqlParameter("@fld_CpyID", DbType.Int32),
            new SqlParameter("@fld_SrvName",DbType.String),
        };
        _para[0].Value = iCompanyId;
        _para[1].Value = gRow.Cells[0].Text;
        string strCmd="";
        if (check.Checked)
        {
            strCmd = "insert into T_subsServ (fld_CpyID,fld_SrvName) values (@fld_CpyID,@fld_SrvName)";
        }
        else
        {
            strCmd = "delete from T_subsServ where fld_CpyID=@fld_CpyID and fld_SrvName=@fld_SrvName ";
        }
        int intReturn = SqlHelper.ExecuteNonQuery(con, CommandType.Text,strCmd, _para);

    }

方法二：指定Button中的Command为Select 在GridView的控件Select事件处理方法中处理数据。

 <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
                        OnPageIndexChanging="GridView1_PageIndexChanging" PageSize="18" OnRowDataBound="GridView1_RowDataBound"
                        OnSelectedIndexChanging="GridView1_SelectedIndexChanging" OnRowDeleting="GridView1_RowDeleting"
                        Height="304px" Width="580px">
                        <Columns>
                            <asp:TemplateField HeaderText="网址">
                                <EditItemTemplate>
                                    <asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("fld_url") %>'></asp:TextBox>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:HiddenField ID="HiddenField1" Value='<%# Bind("fld_urlId") %>' runat="server" />
                                    <asp:Label ID="Label2" runat="server" Text='<%# Bind("fld_url") %>'></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="状态">
                                <EditItemTemplate>
                                    <asp:TextBox ID="TextBox3" runat="server" Text='<%# Bind("fld_Audited") %>'></asp:TextBox>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label ID="Label3" runat="server" Text='<%# Bind("fld_Audited") %>'></asp:Label>
                                </ItemTemplate>
                                <ControlStyle Width="80px" />
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="备注">
                                <EditItemTemplate>
                                    <asp:TextBox ID="TextBox4" runat="server" Text='<%# Bind("fld_comment") %>'></asp:TextBox>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label ID="Label4" runat="server" Text='<%# Bind("fld_comment") %>'></asp:Label>
                                </ItemTemplate>
                                <ControlStyle Width="200px" />
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="公司名称" Visible="false">
                                <EditItemTemplate>
                                    <asp:TextBox ID="TextBox5" runat="server" Text='<%# Bind("CompanyName") %>'></asp:TextBox>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label ID="Label5" runat="server" Text='<%# Bind("CompanyName") %>'></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField ShowHeader="False">
                                <ItemTemplate>
                                    <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
                                        Text="审核" Width="50px"></asp:LinkButton>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField ShowHeader="False">
                                <ItemTemplate>
                                    <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName="Delete"
                                        Text="删除" Width="50px"></asp:LinkButton>
                                </ItemTemplate>
                            </asp:TemplateField>
                        </Columns>
                    </asp:GridView>

后台代码：

protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
    {
        string strState = ((Label)GridView1.Rows[e.NewSelectedIndex].FindControl("Label3")).Text;
        int id = int.Parse(((HiddenField)GridView1.Rows[e.NewSelectedIndex].FindControl("HiddenField1")).Value);
        if (strState == "待批复")
        {
            SqlConnection conn = DbConnection.ConnectSqlDb();
            SqlCommand cmd = new SqlCommand("update t_urlList set fld_Audited=1 where fld_urlId="+id+" ", conn);

            try
            {
                conn.Open();
                cmd.ExecuteNonQuery();
                UrlBind(); 
            }
            catch
            {
                return;
            }
            finally
            {
                conn.Close();
                cmd.Dispose();
                conn.Dispose();
            }
        }
    }
