Question

我使用了sqldatasource（asp.net）的rad网格视图。我检查了自动生成更新和删除列以及自动更新和删除，但是当我点击编辑并更改了一个值然后点击更新链接按钮时没有发生任何事情......甚至没有刷新。但是，删除按钮工作正常。

我该怎么办？

这是我的代码：

<telerik:RadGrid ID="RadGrid1" runat="server" AllowAutomaticDeletes="True" AllowAutomaticUpdates="True" AutoGenerateDeleteColumn="True" AutoGenerateEditColumn="True" DataSourceID="SqlDataSource1" GroupPanelPosition="Top">
            <MasterTableView AutoGenerateColumns="False" DataKeyNames="index" DataSourceID="SqlDataSource1">
                <Columns>
                    <telerik:GridBoundColumn DataField="index" DataType="System.Int32" FilterControlAltText="Filter index column" HeaderText="index" ReadOnly="True" SortExpression="index" UniqueName="index">

只需将Private Sub RadGrid1_InsertCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.InsertCommand RadGrid1.Rebind() End Sub Private Sub RadGrid1_ItemInserted(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridInsertedEventArgs) Handles RadGrid1.ItemInserted RadGrid1.Rebind() End Sub事件调用到代码隐藏中的以下任何一种方法：

private void RadGrid1_InsertCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    RadGrid1.Rebind();
}
private void RadGrid1_ItemInserted(object sender, Telerik.Web.UI.GridInsertedEventArgs e)
{
    RadGrid1.Rebind();
}

如果您使用的是C＃：

sqlcipher

希望这会有所帮助......
