使用onrowdatabound从gridview asp.net c#中的隐藏单元格中获取值

如果你有一个像这样隐藏单元格的gridview

<asp:GridView ID="Timeevents" runat="server" 
        OnRowDataBound="Timeevents_RowDataBound"
        OnRowCommand = "Timeevents_RowCommand"
        AutoGeneratecolumns="false"> 
        <columns>
        <asp:BoundField datafield="CasEID" HeaderText="CasEID" Visible = "false" />
        <asp:BoundField datafield="caseworkerID" HeaderText="CwID" Visible = "false" />
        <asp:BoundField datafield="EventTypEID" HeaderText="EvTypEID" Visible = "false" />
        <asp:BoundField datafield="CaseWorker" HeaderText="Case Worker" />
        <asp:BoundField datafield="EventDate" HeaderText="Event Date" />
        <asp:BoundField datafield="Code" HeaderText="Code" />
        <asp:BoundField datafield="@R_216_10586@lUnits" HeaderText="@R_216_10586@l Units" />
        <asp:BoundField datafield="EventType" HeaderText="Event Type" />
        <asp:BoundField datafield="UnitCost" HeaderText="Unit Cost" />
        <asp:BoundField datafield="@R_216_10586@lCost" HeaderText="@R_216_10586@l Cost"/>
        <asp:TemplateField HeaderText="ADD">
                <ItemTemplate> 
                    <asp:Button  ID="AddUnit" runat="server" Text=" +1 " 
                    CommandName="AddUnit" 
                    CommandArgument='<%# Eval("CasEID")+ ";" + Eval("CaseworkerID")+ ";" + Eval("EventDate")+ ";" + Eval("EventTypEID")+ ";" + ("1")%>'/>
                </ItemTemplate> 
            </asp:TemplateField> 
        </columns>
</asp:GridView>

然后似乎不可能使用(e.Row.Cells [2] .Text)在onRowDatabound处理程序中获取这些值

我通过不将任何BoundFields设置为Visible =“false”解决了这个问题
所以它们是可见的=默认情况下为“true”.在后面的代码中获取onRowDatabound处理程序中所需的值,然后使它们不可见.像这样.

protected void Timeevents_RowDataBound(object sender,GridViewRowEventArgs E)
        {
            if (e.Row.RowType == DataControlRowType.Da@R_800_2301@w)
            {  // just for the da@R_800_2301@ws
                int a = (int.Parse(e.Row.Cells[2].Text));

                if (a % 2 == 0)
                {
                    e.Row.BACkColor = System.Drawing.Color.Gainsboro;
                }
                else
                {
                    e.Row.BACkColor = System.Drawing.Color.White;
                }
            }
            // end if so this applies to header and data rows
            e.Row.Cells[0].Visible = false;
            e.Row.Cells[1].Visible = false;
            e.Row.Cells[2].Visible = false;

        }

是一个相当绿色,它花了我很多的谷歌搜索围绕许多论坛和调试,以确定处理程序无法看到隐藏的数据绑定字段,我似乎无法找到如何基于隐藏字段设置rowcolour的答案所以我虽然id发布此内容供其他人查找

如果任何专家知道更好或替代的方式,也许他们也可以@L_607_23@一些代码/评论
干杯！
