protecte d void gvDetails_RowUpdating（ object sender，GridViewUpdateEventArgs e）
{
// string userid = GridView1.DataKeys [e.RowIndex] .Values [HAU_ID]。ToString（）;
string myfile = GridView1.Rows [e.RowIndex] .Cells [ 1 ]。FindControl（ HAU_ID）。ToString（）;
// int HAUID = Convert.ToInt32（GridView1.DataKeys [e.RowIndex] .Values [HAU_ID ] .ToString（））;

}
解决方案
< asp：GridView ID = GridView1 runat = server AutoGenerateColumns = 错误
CssClass = mGrid DataKeyNames = HAU_ID ShowFooter = true Width = 400px
onrowdeleting = gvDetails_RowDeleting
onrowupdating = gvDetails_RowUpdating>
int HAUID = Convert.ToInt32（GridView1.DataKeys [e.RowIndex] .Values [HAU_ID]。ToString（））;
只需添加datakeyName和一切正确
Asp.net Code
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
CssClass="mGrid" DataKeyNames="" ShowFooter="true" Width="400px"
onrowdeleting="gvDetails_RowDeleting"
onrowupdating="gvDetails_RowUpdating">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton ID="imgbtnDelete" runat="server" CommandName="Cancel" ImageUrl="~/MineBlast/Image/delete.jpg" ToolTip="Cancel" Height="20px" Width="20px" />
</ItemTemplate>
<ItemTemplate>
<asp:ImageButton ID="imgbtnUpdate" CommandName="Update" runat="server" ImageUrl="~/MineBlast/Image/update.jpg" ToolTip="Update" Height="20px" Width="20px" />
</ItemTemplate>
</asp:TemplateField>
<%-- <asp:BoundField DataField="HAU_ID" HeaderText="HAU ID" />--%>
<asp:TemplateField HeaderText="HAUID">
<ItemTemplate>
<asp:TextBox ID="TXtHauID" runat ="server" Text='<%#Eval("HAU_ID") %>' ></asp:TextBox>

</ItemTemplate>
</asp:TemplateField>
</Columns>
<FooterStyle HorizontalAlign="Center" />
<RowStyle HorizontalAlign="Center" />
</asp:GridView>
in aspx.Cs
protected void gvDetails_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
// string userid = GridView1.DataKeys[e.RowIndex].Values["HAU_ID"].ToString();
string myfile = GridView1.Rows[e.RowIndex].Cells[1].FindControl("HAU_ID").ToString () ;
// int HAUID = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Values["HAU_ID"].ToString());
TextBox TextID1 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("TextID1");
TextBox TextID2 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("TextID2");
TextBox TextID3 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("TextID3");
TextBox TextID4 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("TextID4");
TextBox TextID5 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("TextID5");

//cmd.ExecuteNonQuery();
//con.Close();
//lblresult.ForeColor = Color.Green;
//lblresult.Text = username + " Details Updated successfully";
//gvDetails.EditIndex = -1;
//BindEmployeeDetails();
}
解决方案
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CssClass="mGrid" DataKeyNames="HAU_ID""" ShowFooter="true" Width="400px" onrowdeleting="gvDetails_RowDeleting" onrowupdating="gvDetails_RowUpdating">
int HAUID = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Values["HAU_ID"].ToString());
Just add datakeyName and everything right
