After Devexpress CallbackPanel PerformCallback後，不顯示Ext控件

我想在devexpress callbackpanel裏面使用Ext.Net控件。首先呈現頁面時，一切正常，Ext控件都可以。但是，當您使用PerformCallback()函數刷新callback面板時，Ext控件消失。解決辦法是什麼？After Devexpress CallbackPanel PerformCallback後，不顯示Ext控件

此代碼是行不通的，因爲你沒有指定ASPxCallbackPanel.ClientInstanceName屬性（尚未啓用客戶端編程對象）。

修改您的標記如下：

<dx:ASPxCallbackPanel ... ClientInstanceName="cp"> 


<Click Handler="cp.PerformCallback()" />

檢查this演示，說明如何使用ASPxCallbackPanel容器。

問題不在於，我按照您的建議提出，存在同樣的問題。 – serefbilge 2012-02-10 19:09:45

如果你不會運行回調使用JavaScript的前綴「dxis_」後的JavaScript，看看這個topic

您可以添加，和與特定ID例如格，然後再運行腳本，創建ExtJS的控制，配置包含renderTo：'specific di'
