Hello,
I would like to know, how can i handle with the Dialog Close button click event? I need to call a Server side function when the client click on the Dialog Close button.

Hi,
You would just put a regular button inside the dialog and use it the same way as with any other button. The button would have nothing to do with the dialog except for that it is placed inside the dialog. When user clicks the button, the page posts back and trigger your server side event. The dialog automatically closes when the page posts back.
Thanks

Hello again,
Ok, but I want to do it using the pre-build Dialog Close Button placed at the top-right on the Dialog. Is it possible?
Thanks

Hi, The close button does not trigger any server event directly. However it does trigger client side JavaScript event: http://doc.essentialobjects.com/library/1/eo.web.dialog.clientsideoncancel.aspxYou can write a JavaScript handler for this event and then trigger a post back from your JavaScript code (for example, calling __doPostBack). You will need to code accordingly so that your server side code can distinguish the post back is from your JavaScript code. Thanks

Hi,
Ok, I got it! But, now the problem is I'm writing the javaScript _doPostBack on the dialog.ClientSideOnCancel and it doesnt trigger anything. Do I have to set as True any PostBack property of the dialog?
My code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim PostBackStr As String
PostBackStr = Page.ClientScript.GetPostBackEventReference(Me, "ClosePostBack")
Dialog2.ClientSideOnCancel = PostBackStr
If Page.IsPostBack Then
Dim eventArg As String = Request("__EVENTARGUMENT")
If eventArg = "ClosePostBack" Then
MsgBox("It works!")
End If
End If
End Sub
Thanks,

Hi,
ClientSideOnCancel takes a JavaScript function name, not Javascript code. So you will need to have a client side JavaScript function first.
Thanks
