我要把<asp:BoundField Visible="False" DataField="ProjectId" HeaderText="ProjectId"></asp:BoundField>中的Visible="False"去掉后台id才能取到值！可是这个列又不能显示出来！高手能帮忙解决一下吗？

Answer 1

<asp:HiddenField ID="HiddenFieldId" runat="server" Value='<%# Eval("ProjectId") %>' />用隐藏域存ProjectId，取的时候从隐藏域里面取就可以了

Answer 2

http://topic.csdn.net/u/20100115/15/d4c41926-9e50-4fe7-8030-96d0d59b01b9.html
这里不是有答案了？

Answer 3

如果用RowCommand，可以这样取ProjectIdif (null != e.CommandArgument)
{
    int ProjectId = Convert.ToInt32(e.CommandArgument);
}

Answer 4

是啊
  你隐藏ID列
  也可以从上次的方法获取啊
你上次用的我第一个方法
直接gridview.rows.cell
 我不是还有另外一种 
获取隐藏列的方法也发给你了么

Answer 5

<asp:HiddenField ID="ooxx" runat="server" Value='<%# Eval("ProjectId") %>' />
                                </asp:HiddenField> 你确定GridView  里面有这个属性？

Answer 6

            GridViewRow gvrow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
            int index = gvrow.RowIndex;
            //string id = DVClientInfo.Rows[index].Cells[1].Text.ToString();
            string tNumber = DVClientInfo.DataKeys[index].Values["ProjectId"].ToString();index 会数组溢出？

Answer 7

不是index的问题
是你ProjectId 没有存放在datakeys中吧

Answer 8

应该是这个问题。。只要Gridview没错，应该不会溢出啊！

Answer 9

前台绑定参数CommandArgument；<asp:LinkButton ID="lbtn_redact" runat="server" CommandName="redact" CommandArgument='<%# Bind("id") %>' ForeColor="#0099FF">编辑</asp:LinkButton>
后台取值if (e.CommandName == "redact")//编辑
{ 
   e.CommandArgument = "取值"
}

Answer 10

在左边工具栏 -->“标准”栏里面，你找找，拖进去设置一下就行了，和Gridview没关系

Answer 11

<asp:GridView ID="DVClientInfo" runat="server" DataKeyNames="Grup"这样？

Answer 12

你查数据的时候，ProjectId查出来了吗？
要不你把你查询数据的代码发出来看看

Answer 13

gridview属性栏有个DataKeys 
输入ProjectId 就OK
或者在源码中
<asp:GridView ID="GridView1" runat="server" DataKeyNames="ProjectId">
                    </asp:GridView>

Answer 14

当我把 Visible="False" 去掉就可以查出来/// <summary>
        /// 生成事件时激发
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void DVClientInfo_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            //int strProjectId = Convert.ToInt32(e.Item.Cells[0].Text);
            int strProjectId = 0;            GridViewRow gvrow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
            int index = gvrow.RowIndex;
            string id = DVClientInfo.Rows[index].Cells[1].Text.ToString();
            if (e.CommandName == "redact")//编辑
            {             }
            else if (e.CommandName == "forbid")//禁用
            {
                bool temp = centaline.Pro.ClassLibrary.Property.CProject.UpStatusF(strProjectId);
            }
            else if (e.CommandName == "comeback")//恢复
            {
                bool temp = centaline.Pro.ClassLibrary.Property.CProject.UpStatusR(strProjectId);
            }
        }

Answer 15

 datakeys 属性加哪里呀？怎么加呀？

Answer 16

不用Visible="False" 你别往GridView里面邦这一列不就不显示projectId了吗

Answer 17

<asp:GridView ID="DVClientInfo" runat="server"onrowdatabound="DVClientInfo_RowDataBound" onrowcommand="DVClientInfo_RowCommand">
                            <Columns>
                                <asp:TemplateField>
                                <HeaderTemplate>
                                  <input id="Checkbox2" type="checkbox" runat="server" /><label>全选</label>
                                </HeaderTemplate>
                                <Headerstyle ForeColor="#333333" Height="24px" Width="60Px" Wrap="False" />
                                <Itemstyle HorizontalAlign="Center" Height="24px" />
                              </asp:TemplateField>
                                <asp:BoundField DataField="ProjectName" HeaderText="项目名称" >

                                </asp:BoundField>
                                <asp:TemplateField HeaderText="操作">
                                    <ItemTemplate>
                                        <asp:LinkButton ID="lbtn_redact" runat="server" CommandName="redact" ForeColor="#0099FF">编辑</asp:LinkButton>
                                        <asp:LinkButton ID="lbtn_forbid" runat="server" CommandName="forbid" ForeColor="#0099FF">禁用</asp:LinkButton>
                                        <asp:LinkButton ID="lbtn_comeback" runat="server" CommandName="comeback" ForeColor="#0099FF">恢复</asp:LinkButton>
                                    </ItemTemplate>
                                    <Itemstyle HorizontalAlign="Center" />
                                </asp:TemplateField>
                            </Columns>
                        </asp:GridView>
这样行了，不要projectId，你绑它干嘛

Answer 18

绑他有用！呵呵！所用处理都要用到projectId！

Answer 19

HTML code
<asp:HiddenField ID="HiddenFieldId" runat="server" Value='<%# Eval("ProjectId") %>' />
用隐藏域存ProjectId，取的时候从隐藏域里面取就可以了
