I have sample page which displays the search result on GridView which has Edit and Delete functionality and its working fine, and when i transferred my page for Atlas Frame work, edit and delete functionality is giving me java script error (Object not found). but search button is able populates the Grid View with out page refresh.

Odd, I've done multiple pages with editable GridViews with no problem.

Now, do you have the GridView doing anything client side? If so, that may be what's causing the script errors.

Thanks for reply! i started using Atlas just from yesterday and i'm not sure where i'm wrong, i just put my grid view in update panel control and without defining triggers element for bubbled events, is that correct that i did or something i'm missing, Could it be possible for you to send me the code where you handled edit, update cancle events on code behind files.

Thank you so much.

hello.

well, it would be even easier for us if you can build a repro page that works (ie, can't you build a page and paste it here so that we can simply copy and run it and see if we can discover what's going on?).

thanks.

Hi Luis Thanks for reply, i did so many R& D s on that and finally got the solution, but the problen is due to some bugs in Atlas Framework and i would like to share my code and i dont have web space to publich the page so sorry i'm going to paste it here you just copy and paste that code in new page.and when you click show it shows grid and u are not able to fire events for edit and delete it gives javascript error "object expected" but when you add attribute to form tag defaultbutton="Button1" then code runs fine. what is that Bug.

Here is the ASPX file

hello.

well, you've jot another atlas bug. the problem is that your initial page doesn't generate the traditional client code script block that initializes the potback. during the atlas callback, the server sends that script block but unfortunatelly the client atlas framework filters it and doesn't add it to the client script block since it thinks that it's already there. you can check this by looking at the debug/atlas.js, method _updateScripts:

if (text) {
if (text.indexOf('function __doPostBack(') >= 0) {
continue;
}

scriptText += text;

}

so, your best option is to:
1. use the defaultbutton because that will automatically generate the necessary code
2. use one of the getXXXreference method of the clientscriptmanager class.

for 2 to work, try to add this to your page:

Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
MyBase.OnLoad(e)

If Not Me.IsPostBack Then
Me.ClientScript.GetPostBackEventReference(Me, "")

End If
End Sub

hope this helps.

This just solved pretty much every issue I've had with Atlas so far.

Thank you Luis!
