Question

查了好多
还是没有解决源：

            string b = GridView2.SelectedRow.Cells[2].Text.ToString();
            string c = GridView2.SelectedRow.Cells[3].Text.ToString();
            //string d = GridView2.SelectedRow.Cells[4].Text.ToString();

Answer 1

int index = Gridview1.SelectedIndex;
string e1 = GridView2.DataKeys[index]["cys_zzjg"].ToString();

Answer 2

<dxwgv:ASPxGridView ID="agvTestItemBill" runat="server" Width="100%" KeyFieldName="TESTSTANDARDID"
            ClientInstanceName="grid" AutoGenerateColumns="False" 
            DataSourceID="ObjectDataSource1" 
            oncustomcallback="agvTestItemBill_CustomCallback">
            <SettingsPager PageSize="10"></SettingsPager>
            <Columns>
                <dxwgv:GridViewDataTextColumn FieldName="TESTSTANDARDID" Visible="false" VisibleIndex="0">
                </dxwgv:GridViewDataTextColumn>
 </Columns>
            <ClientSideEvents CustomButtonClick="function(s,e){GridCustomButtonClick(s,e); }" />
        </dxwgv:ASPxGridView>
                <dxwgv:GridViewDataTextColumn FieldName="STANDARDSOURCEURL" Visible="false" VisibleIndex="1">
                </dxwgv:GridViewDataTextColumn>这个第三方控件。
去这两个隐藏列的值在前台JS里面就行，这是两个参数的，一个参数的就是那个res就是你想要的那个值。function GridCustomButtonClick(s,e)
{
    gridvisibleIndex = e.visibleIndex;
    grid.GetRowValues(gridvisibleIndex ,'TESTSTANDARDID;STANDARDOBJECTTYPE',GridViewValuesCallbackDetail);        
}function GridViewValuesCallbackDetail(res){
    var id = res[0];
    var S_type  = res[1];
}

Answer 3

后台可以使用DataBinder.Eval方法
或者不要用visible属性隐藏列：
 <style type="text/css">
        .hidden { display:none;}
 </style>
<asp:BoundColumn DataField="OtherAppAmt">
                    <FooterStyle  CssClass="hidden"/> 
                    <HeaderStyle CssClass="hidden"/>
                    <ItemStyle CssClass="hidden" />
                </asp:BoundColumn>

Answer 5

在gridview中SelectedIndexChanged事件里,根本就没有e.rowindex属性,你根本就取不出来.你怎么取?
rowindex是在更新或者编辑里才用到的-----------------------(object sender, GridViewUpdateEventArgs e)
{
   才会取到编辑行e.rowindex
}int index = Gridview1.SelectedIndex;//取得编辑行string e1 = GridView2.DataKeys[index]["cys_zzjg"].ToString();

Answer 6

 int index = this.GridView2.SelectedIndex;            string a = GridView2.SelectedRow.Cells[1].Text.ToString();
            string b = GridView2.SelectedRow.Cells[2].Text.ToString();
            string c = GridView2.SelectedRow.Cells[3].Text.ToString();
            string d = GridView2.DataKeys[index]["cys_yyzz"].ToString();
            string e1 = GridView2.DataKeys[index]["cys_zzjg"].ToString();
            string f = GridView2.DataKeys[index]["cys_swdjh"].ToString();
            string g = GridView2.DataKeys[index]["cys_khxkzh"].ToString();
            string h = GridView2.DataKeys[index]["cys_dlysxk"].ToString();
            string i = GridView2.DataKeys[index]["cys_frxm"].ToString();
            string j = GridView2.DataKeys[index]["cys_frsfz"].ToString();
            string k = GridView2.SelectedRow.Cells[11].Text.ToString();
            string l = GridView2.DataKeys[index]["cys_xkz"].ToString();这行开始报：未将对象引用设置到对象的实例。的错误
            string m = GridView2.DataKeys[index]["cys_khxxdz"].ToString();
            string n = GridView2.DataKeys[index]["cys_zltxrz"].ToString();
            string o = GridView2.DataKeys[index]["cys_cym"].ToString();
            string p = GridView2.DataKeys[index]["cys_sf"].ToString();
            string q = GridView2.DataKeys[index]["cys_ds"].ToString();
            string r = GridView2.DataKeys[index]["cys_zgdw"].ToString();
            string s = GridView2.DataKeys[index]["cys_yhzh"].ToString();
            string t = GridView2.SelectedRow.Cells[20].Text.ToString();
            string u = GridView2.DataKeys[index]["cys_lxrdh"].ToString();
            string v = GridView2.DataKeys[index]["cys_fsjg"].ToString();
            string w = GridView2.DataKeys[index]["cys_hylb"].ToString();
            string x = GridView2.SelectedRow.Cells[24].Text.ToString();
            string y = GridView2.DataKeys[index]["cys_jbrxm"].ToString();
            string z = GridView2.DataKeys[index]["cys_jbrdh"].ToString();

            string a4 = GridView2.DataKeys[index]["cys_zyyw"].ToString();
            string a5 = GridView2.SelectedRow.Cells[31].Text.ToString();
            string a6 = GridView2.DataKeys[index]["cys_tqjl"].ToString();
            string a7 = GridView2.DataKeys[index]["cys_ywwl"].ToString();
            string a8 = GridView2.SelectedRow.Cells[34].Text.ToString();
            string a9 = GridView2.DataKeys[index]["cys_czh"].ToString();

Answer 7

protected void GridView_RowCreated(object sender, GridViewRowEventArgs e)
  {
  if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header)
  {
  e.Row.Cells[1].Visible = false;
  e.Row.Cells[2].Visible = false;
  }
  }
取值：
GridView.Rows [i].Cells [1].Text  或
<asp:HiddenField ID="Hd_SH" Value='<%#DataBinder.Eval(Container.DataItem,"BH")%>' runat="server" />
或
  <asp:BoundField DataField="BH" HeaderText="">
<ControlStyle CssClass="hidden" />
<FooterStyle CssClass="hidden"/>
<HeaderStyle CssClass="hidden"/>
<ItemStyle CssClass="hidden"/>
</asp:BoundField>
.hidden
{
display:none;
}

Answer 8

protected void GridView_RowCreated(object sender, GridViewRowEventArgs e)
  {
  if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header)
  {
  e.Row.Cells[1].Visible = false;
  e.Row.Cells[2].Visible = false;
  }
  }
取值：
GridView.Rows [i].Cells [1].Text  或
<asp:HiddenField ID="Hd_SH" Value='<%#DataBinder.Eval(Container.DataItem,"BH")%>' runat="server" />
或
  <asp:BoundField DataField="BH" HeaderText="">
<ControlStyle CssClass="hidden" />
<FooterStyle CssClass="hidden"/>
<HeaderStyle CssClass="hidden"/>
<ItemStyle CssClass="hidden"/>
</asp:BoundField>
.hidden
{
display:none;
}

Answer 9

不要用visible属性隐藏列：
 <style type="text/css">
  .hidden { display:none;}
 </style>

Answer 10

 前台:
DataKeyNames="cys_yyzz,cys_zzjg,cys_swdjh,cys_khxkzh,cys_dlysxk,cys_frxm,cys_frsfz">
后台
string l = GridView2.DataKeys[index]["cys_xkz"].ToString();
DataKeys[index][string].ToString(),  string是要与DataKeyNames里面的对应的,你没有的话,是去不出来的.
你已经绑定的字段,你就用 string a = GridView2.SelectedRow.Cells[1].Text.ToString();
你隐藏的列,才用string l = GridView2.DataKeys[index]["cys_xkz"].ToString();
不是每行都用DataKeyS[index]

Answer 11

没有隐藏的我用的是            string a = GridView2.SelectedRow.Cells[1].Text.ToString();
            string b = GridView2.SelectedRow.Cells[2].Text.ToString();
            string c = GridView2.SelectedRow.Cells[3].Text.ToString();隐藏的我用的是：
string d = GridView2.DataKeys[index]["cys_yyzz"].ToString();
            string e1 = GridView2.DataKeys[index]["cys_zzjg"].ToString();
            string f = GridView2.DataKeys[index]["cys_swdjh"].ToString();
            string g = GridView2.DataKeys[index]["cys_khxkzh"].ToString();
            string h = GridView2.DataKeys[index]["cys_dlysxk"].ToString();
            string i = GridView2.DataKeys[index]["cys_frxm"].ToString();
            string j = GridView2.DataKeys[index]["cys_frsfz"].ToString();
