gridview 在编辑状态只能获取datakeys的值，获取其它列的值会出现（索引超出范围）
在网上搜了很久，不能解决。gridview在RowUpdating事件处理正常；但在rowupdating事件中获取其它列的值时出错。请高手帮忙看看设置了if (!IsPostBack)处理；设置了主键；主要后台代码（c#）
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GridViewBind();
}
}
protected void GridViewzfxx_RowEditing(object sender, GridViewEditEventArgs e)
{
GridViewzfxx.EditIndex = e.NewEditIndex;
GridViewBind();
}
protected void GridViewzfxx_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string id = GridViewzfxx.DataKeys[e.RowIndex].Value.ToString().Trim();
string zfje = GridViewzfxx.Rows[e.RowIndex].Cells[2].Text.ToString().Trim();//运行这条代码时出现索引超出范围的错误
} --------------------编程问答-------------------- 你第3列是模板列吗？ --------------------编程问答-------------------- 没使用模板列。试过模板列GridViewzfxx.Rows[e.RowIndex].FindControl["htje"].Text.ToString().Trim();提示同样的错误。郁闷
前台gridview定义代码
<asp:GridView ID="GridViewzfxx" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" onpageindexchanging="GridViewzfxx_PageIndexChanging"
onrowcancelingedit="GridViewzfxx_RowCancelingEdit"
onrowdeleting="GridViewzfxx_RowDeleting" onrowediting="GridViewzfxx_RowEditing"
onrowupdating="GridViewzfxx_RowUpdating" Width="581px">
<Columns>
<asp:BoundField DataField="id" Visible="False" />
<asp:BoundField DataField="htbh_new" HeaderText="合同编号" ReadOnly="True" />
<asp:BoundField DataField="zfje" HeaderText="支付金额(元)" />
<asp:BoundField DataField="zfsj" DataFormatString="{0:yyyy-MM-dd}"
HeaderText="支付时间" />
<asp:CommandField HeaderText="编辑" ShowEditButton="True" CausesValidation="false"/>
<asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
</Columns>
</asp:GridView> --------------------编程问答-------------------- 还有个问题在“编辑”commandfield不配置CausesValidation="false"，不能触发 rowupdating事件，不知道为什么？ --------------------编程问答-------------------- --------------------编程问答-------------------- 若是非模版列：
string zfje =((TextBox)GridViewzfxx.Rows[e.RowIndex].Cells[2].Controls[0]).Text; --------------------编程问答-------------------- 谢谢楼上的，我就是用这个语句，报index超出范围 --------------------编程问答-------------------- 执行这行代码也报index超出范围：GridViewRow row = GridViewzfxx.Rows[e.RowIndex];
但这行代码string id = GridViewzfxx.DataKeys[e.RowIndex].Value.ToString().Trim();
又能通过并获取的值正确。 --------------------编程问答-------------------- 这是完整代码：

--------------------编程问答-------------------- 顶,我也碰这样的问题,求解~~~ --------------------编程问答-------------------- 代码太长。。
这种问题一般都是ROWINDEX多或者CELL 了
Rows[e.RowIndex].Cells[2]
你看看这两个值 是否都满足你的GRIDVIEW
补充：.NET技术 , ASP.NET
