网格视图编辑问题

我有可编辑的网格视图，如果我点击任何一行的编辑，比如"x"，它会在编辑模式下打开，但如果我点击其他任何一行，比如"y"，"x"应该取消编辑。但在我的代码中，单击"y"后，这两行仍处于编辑模式。

protected void gvViewAdmins_RowEditing(object sender, GridViewEditEventArgs e)
{
    gvViewAdmins.EditIndex = e.NewEditIndex;
    Label lblEmailId = gvViewAdmins.Rows[e.NewEditIndex].FindControl("gvlblEmail") as    Label;
    lblEmailId.Visible = false;
    ViewState["currentEmailId"] = lblEmailId.Text;
    TextBox textboxEmailId = gvViewAdmins.Rows[e.NewEditIndex].FindControl("gvtbEmailId") as TextBox;
    textboxEmailId.Text = ViewState["currentEmailId"].ToString();
    textboxEmailId.Visible = true;
    Label lblRole = gvViewAdmins.Rows[e.NewEditIndex].FindControl("gvlblRole") as Label;
    lblRole.Visible = false;
    ViewState["currentRole"] = lblRole.Text;
    DropDownList dropdownRoles = gvViewAdmins.Rows[e.NewEditIndex].FindControl("gvddlRoles") as DropDownList;
    this.PopulateRole(dropdownRoles);
    dropdownRoles.Visible = true;
    this.SelectRoleDropDownValue(dropdownRoles);
    LinkButton lbtnUpdate = gvViewAdmins.Rows[e.NewEditIndex].FindControl("lbtnUpdate") as LinkButton;
    LinkButton lbtnCancel = gvViewAdmins.Rows[e.NewEditIndex].FindControl("lbtnCancel") as LinkButton;
    LinkButton lbtnEdit = gvViewAdmins.Rows[e.NewEditIndex].FindControl("lbtnEdit") as LinkButton;
    lbtnUpdate.Visible = true;
    lbtnCancel.Visible = true;
    lbtnEdit.Visible = false;
}

我的代码出了什么问题？

网格视图编辑问题

查看您的代码后，您似乎没有使用gridview的默认编辑功能。你只是设置控件可见属性打开和关闭。

更好的方法是，分别定义项目模板和编辑项目模板，如

标记：

<asp:GridView ID="objGridView" runat="server" AutoGenerateColumns="false" onRowEditing="objGridView_RowEditing">
  <columns>
     <asp:TemplateField HeaderText="">
        <ItemTemplate>
          <asp:Label ID="lblEmailID" runat="server" Text='<%#Eval("<<EmailID Field>>")%>' />
        </ItemTemplate>
        <EditItemTemplate>
          <asp:TextBox ID="txtEmailID" runat="server" Text='<%#Eval("<<EmailID Field>>")%>'/>
        </EditItemTemplate>
     </asp:TemplateField>
  </columns>
</asp:GridView>

代码背后：

protected void objGridView_RowEditing(object sender, GridViewEditEventArgs e)
{
  objGridView.EditIndex = e.NewEditIndex;
  <<BindGrid Again>>
}
