gridview有一列其中单元格式空的 列代码：<asp:BoundField HeaderText="列名称" DataField="fieldName" HeaderStyle-Width="15%" /> js赋值的时候是document.getElementById("gvwExcelField").rows(3).cells(1).innerHTML="C_Name" 然后在Gridview中这个值也显示出来了 但是在后台取的时候 string xx = gvwExcelField.Rows[3].Cells[1].Text; xx总是等于" " 求解！

后台的话怎么获取呢 怎么获取 列名称 这一列的 每个单元格的值呢

后台代码获取

using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;

{ }
protected void Button1_Click(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('" + Request.Form["slT"] + "')", true);
}
}
这里就是获取select控件js赋值的
<ItemTemplate>
<asp:Label ID="lblFiledName" runat="server" Text='<%# Eval("FieldName") %>' [color=#FF0000]name="lblFiledName"></asp:Label>[/color] <asp:HiddenField ID="hidFiled" runat="server" />
</ItemTemplate>
</asp:TemplateField>
怎么取不一样啊
int index = int.Parse(e.CommandArgument.ToString());
Label lblcontactNos = this.gvwExcelField.Rows[index].FindControl("lblFiledName") as Label; string lblcontactNos = lblcontactNos.Text.ToString();
<ItemTemplate>
<asp:Label ID="lblFiledName" runat="server" Text='<%# Eval("FieldName") %>' name='<% Eval("columnSortID")%>'></asp:Label> <asp:HiddenField ID="hidFiled" runat="server" />
</ItemTemplate>
</asp:TemplateField>用columnSortID命名不行吗
OnRowCommand="gvwExcelField_RowCommand">
<Columns>
<asp:BoundField HeaderText="序号" DataField="columnSortID" HeaderStyle-Width="6%" HeaderStyle-Height="35" />
<asp:TemplateField HeaderText="列名称" HeaderStyle-Width="15%">
<ItemTemplate>
<asp:Label ID="lblFiledName" runat="server" Text='<%# Eval("FieldName") %>' name="lblFiledName"></asp:Label>
<asp:HiddenField ID="HidFiledName" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="对应操作" HeaderStyle-Width="15%">
<ItemTemplate>
<asp:ImageButton ID="IbtRowUp" runat="server" ImageUrl="~/Import/Images/uparrow.gif"
Style="cursor: pointer" CommandName="row_up" CommandArgument='<%#DataBinder.Eval(Container.DataItem,"columnSortID")%>' />
<asp:ImageButton ID="IbtRowDown" runat="server" ImageUrl="~/Import/Images/downarrow.gif"
Style="cursor: pointer" CommandName="row_down" CommandArgument='<%#DataBinder.Eval(Container.DataItem,"columnSortID")%>' />
<img src="Images/field.gif" style="cursor: pointer" alt="修改字段" onclick="ModifyExcelFiled('<%#Eval("columnSortID") %>')" />
<img src="Images/del_None.gif" style="cursor: pointer" alt="清除字段" onclick="DeleteExcelFiled('<%#Eval("columnSortID") %>')" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>下面是给单元格赋值 在模板列里放置一个Label和一个HiddenFiled 给空单元格赋值的时候同时值赋给这两个空件 if (win) {
var obj = document.getElementById("gvwExcelField");
obj.rows(rowCount - 1 + 1).cells[1].childNodes[0].innerText = win;
obj.rows(rowCount - 1 + 1).cells[1].childNodes[1].value = win;
}
取值的时候 先取Label的值 如果Label的值为空(label取到的值一定为空) 就取HiddenFiled的值 string ExcelFiled = ((Label)gvwExcelField.Rows[b].FindControl("lblFiledName")).Text;
if (ExcelFiled == "")
{
ExcelFiled = ((HiddenField)gvwExcelField.Rows[b].FindControl("HidFiledName")).Value;
}
if (ExcelFiled != "")
{
//此处代码省略
}
