RadGrid与GridView

标签： c# asp.net telerik radgrid

我正在将gridview迁移到RadGrid。我正在努力更新我的RadGrid行，我遇到了一些问题。

我在“Inplace”editmode中更新Clarify Account Nbr，site id，Quote ID列。让我们说在更新之前我的值为200,300,400列Clarzed Account Nbr，网站ID，报价ID。当我单击编辑按钮并将值更改为111,222,333。当我调试我的代码并尝试查看textbox.text值它显示旧值（200,300,400）而不是新值（111 ，222,333）。 （我希望你们都明白我的问题）。我在哪里做错了。请帮帮我。

我看到了这个链接，但没有用。

如果您看到以下代码

string ClarifyAccountNbr = (editedItem["Clarify Account Nbr"].Controls[0] as TextBox).Text;
string SiteID = (editedItem["Site ID"].Controls[0] as TextBox).Text;
string QuoteID = (editedItem["Quote ID"].Controls[0] as TextBox).Text;

当我调试并指向ClarifyAccountNbr，SiteID，QuoteID时，我得到的旧值不是新值。（更新前）

这是我的代码：

防弹方法是从列编辑器中获取新数据，如此Telerik演示中所示：

希望这有帮助。
