First download and install the ASP.Net Ajax Framework, after that just add an update panel on the page. Now add the controls inside the update panel (like you are creating a regular page). after adding all the controls and code for the controls. just change the Property of the Update Panel by Adding all the click events of all the 3 buttons as Triggers of Update Panel. and its done.

or you can search on google for "ASP.Net using AJAX UpdatePanel". Also there is very nice video tutorial on "ajax.asp.net". I suggest you to watch all the ajax videos on that web site.

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.

Abhijit Jana19-Aug-08 4:43

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) Wink | ;)

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("$"))
