How to refresh parent page grid when close radwindow?
提问by Joe Yan
In the parent page, it had a preview button to prompt a radwindow.
在父页面中，它有一个预览按钮来提示一个 radwindow。
How can I refresh the grid in parent page when user click the Close [X] button of the radwindow.
当用户单击 radwindow 的关闭 [X] 按钮时，如何刷新父页面中的网格。
The radwindow generate in code behind:
radwindow 在后面的代码中生成：
Protected Sub rtbMenu_ButtonClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadToolBarEventArgs) Handles rtbMenu.ButtonClick
If e.Item.Value = "Preview" Then
Dim url = "~/TrainingAdmin/SIMPER_view.aspx?SIMPER_ID=0&UserID=" & Request.QueryString("UserID") & "&From=" & RadDatePicker_ValidFrom.SelectedDate & "&To=" & RadDatePicker_ValidTill.SelectedDate
Dim windowManager As New RadWindowManager()
Dim window1 As New RadWindow()
' Set the window properties
window1.NavigateUrl = url
window1.ID = "RadWindow1"
window1.Height = 750
window1.Width = 740
window1.Top = 140
window1.Left = 250
window1.AutoSize = False
window1.VisibleTitlebar = True
window1.VisibleStatusbar = False
window1.VisibleOnPageLoad = True
' Set this property to True for showing window from code
windowManager.Windows.Add(window1)
Me.Form.Controls.Add(window1)
ElseIf e.Item.Value = "Refresh" Then
Response.Redirect("~/TrainingAdmin/SIMPER_details.aspx?userID=" & Request.QueryString("UserID"))
End If
End Sub

Take a look here: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window. This demo from Telerik shows how you can use the OnClientCloseevent of the RadWindow control to initiate a partial postback that will update the grid. Note that a lot of the code is in the main page where the grid is, not in the content page loaded in RadWindow.
看看这里：http: //demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window。Telerik 的这个演示展示了如何使用RadWindow 控件的OnClientClose事件来启动将更新网格的部分回发。请注意，很多代码位于网格所在的主页面中，而不是在 RadWindow 中加载的内容页面中。
This approach for opening a RadWindow from the code-behind is better in case you cannot use the client-side logic from the demo: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx.
如果您无法使用演示中的客户端逻辑，这种从代码隐藏打开 RadWindow 的方法会更好：http: //www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow -from-the-server.aspx。
