rad網格視圖更新不會導致刷新

Question

我將rad網格視圖與sqldatasource（asp.net）一起使用。 我檢查了“自動生成更新和刪除”列以及“自動更新和刪除”列，但是當我單擊“編輯”並更改了一個值，然后單擊“更新鏈接”按鈕時，沒有任何反應...甚至沒有刷新。 但是，刪除按鈕可以正常工作。

我該怎么辦？

這是我的代碼：

只需將Radgrid1.Rebind事件調用到代碼隱藏中的以下任何一種方法中：

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

如果您使用的是C＃：

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();
}

希望這可以幫助...
