推荐答案

您 u 可以使用Rowedititng属性..

Youu can use Rowedititng property..

<Columns>
       <asp:TemplateField HeaderText="Filed">

            <ItemTemplate>
              <asp:Label runat="server" ID="category" Text='<%#Eval("field1") %>' />
            </ItemTemplate>

            <EditItemTemplate>
            <asp:TextBox runat="server" ID="txt1" Text='<%#Eval("filed1") %>' ValidationGroup="v1" />
            <asp:RequiredFieldValidator runat="server" ID="req1" ControlToValidate="txt1" ErrorMessage="*" ValidationGroup="v1" />
            </EditItemTemplate>


         </asp:TemplateField>

          <asp:TemplateField HeaderText="Action">

      <ItemTemplate>
      <asp:LinkButton ID="btnEdit" Text="Edit" runat="server" CommandName="Edit" />&nbsp;&nbsp;
      <asp:LinkButton ID="btnDelete"  Text="Delete" runat="server" CommandName="Delete" />
      </ItemTemplate>

      <EditItemTemplate>
      <asp:LinkButton ID="btnUpdate" Text="Update" runat="server" CommandName="Update" ValidationGroup="v1" />
      <asp:LinkButton ID="btnCancel" Text="Cancel" runat="server" CommandName="Cancel" />
      </EditItemTemplate>

              <ControlStyle ForeColor="#6600FF" />

              <ItemStyle Font-Size="Medium" />

      </asp:TemplateField>


       </Columns>

$ b

比在row_editing属性中.....

than in row_editing property.....

GridView1.EditIndex = e.NewEditIndex;
       BindGridData();

BindGridData中的
你 u 可以用你选择的字段绑定你的网格。



现在，row_Updating属性

in BindGridData youu can bind your grid with selected field.

now,row_Updating Property

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
        
        TextBox txt1 = (TextBox)row.FindControl("txt1");
        GridView1.EditIndex = -1;
        string s="update query";
        Sqlcommand cmd=new Sqlcommand(s,connection object);
 cmd.executenonquery();

BindGridData();
}

希望你得到它并解决你的问题。
