Hi guys,
we have a requirement of calling a web service to update some information in our clients db.
Now everything is working fine, but what if for some reason web service call fails?
call has to be realtime from web app for first time. In case of failure repetitive calls can be using any other service.
thanks
Keep DotNetting!!

You can use AJAX framework to handle the exceptions from webservice.
Have a look at it[^].

how do i get the recently selected index of CheckBoxList.
say i have a CheckBoxList with 5 items and the first one is selected. I select the last item and i want the index of the last item i selected.
|

you can do one thing. just add selected index in a Collection Called Stack , [ in .NET there is Class Called Stack ]
and when you want to retreive the Recent selcted index , popuout the stack.
Hope you got it !!
cheers,
Abhijit

What about having a member integer variable and assigning it with the last selected index.
You will save the overhead of stack(push and pop)

Maite, with last SelectedIndex it means the SelectedIndex itself.
I hope you that it has property called SelectedIndex.

Just in case you didnt notice it, it is a checkboxlist not a dropdownlist or radiobuttonlist
Checkboxlist controls can have many selecteditems, and selectedindex wont always return the last selectedindex

Im not sure if this is what you are asking
But if you wanna know what item was clicked and caused a postback
You need to have autopostback = true for the checkboxlist
'Get the object's full name
Dim x As String = Request.Form("__EVENTTARGET")
'Get only the value in case you are using values for each item
Dim Index As Integer = x.Substring(x.LastIndexOf("$"))

Use recursion.
Sub AddNodeName(ByVal node As TreeNode, ByRef Path As StringBuilder)
If node.Level > 1 Then
AddNodeName(node.Parent, Path)
OrgText.Append("/") 'exchange / for whatever delimiter you want
End If
Path.Append(node.Text)
End Sub

Hi ,
I want to clear all my session variables when the page terminates.
I tried page_unload , but then for every refresh (submit) of the page,
control goes to this function?
How I can have a function which only executes at the page termination?
regards
Vijay

You haven't taken time to read the documentation. It explains what page_unload does and the behaviour you are getting is how it works.

What do you meant by "page termination" ? When someone tries to close the browser ?

|

use Global.asax file , use Session_End() to Session Abandon. Call when you terminating the page.
Now, you can do it from you application easily, but how to do in Browser Close, there are some Trick. First try it. then I can help you

Hi Abhijit,
I can not use session_end. I am not exiting my session. I am just terminating a page from my session and I want to find out where I can catch this.
I tried javascript onUnload but it goes there everytime the postback happens

Vijay

yes , Page_unload Called on every post back.
use one condition to check clientX and clientY , it should be negative when you click [X] , File -> Close and Alt + 4 else it should be postive.
so just check that condition
Hope you have got my point.
cheers,
Abhijit
