I have been working for quite some time on this issue which in theory
should be quite simple. The problem is that the Cancel and Save
events are not fired when their respective buttons are clicked.
I have read several posts which say to put your column generating
section in the Page_Init section and it will solve the
problem....howe ver, it hasn't solved mine.
Can somebody please take a look at this and provide any insight if
possible?
Thanks,
Mark

Mark,
Make sure that viewstate is on and that the grid is recreated every page
load.
If these two things are done it should be working.
If you'd like me to take a look at the code post it and I'll see if I can
get it to work.

Mark,
Sorry I just wasn't specific. I'll chalk up my lack of presenting a logical
request to the amount of sleep I had at the time. :)
Could you please also post the designer's code. Then I can recreate the
entire page and take a look.

Mark,
It took a little while of playing to get it to work, but as it turns out all
I did was move the Call BindData() statement which is in the Page_Init sub
so that it is below the call to: InitializeCompo nent
(I should have seen it without recreating everything!)
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form Designer
'Do not modify it using the code editor.
InitializeCompo nent()
Call BindData()
End Sub

Mark,
Everything seems to be working for me. I would suggest however that you look
into creating your datagrid in a user control and add the user control to
the page dynamically. That way a lot of the page rendering and post back
event handlers are created for you.
Take a look at the code I offer on my website: www.aboutfortunate.com on
placing user control's on a page dynamically. It should get you started.
Just search for: Dynamic User Controls
I hope this helps.

news:e4******** ******@TK2MSFTN GP12.phx.gbl... Justin,
Thanks for looking at this.
How many times does the dgData_cmdEdit event get called when you request
the page? Every time I request the page, this event runs twice (I don't have
Zone Alarm). If I remove the AddHandler section, then it only runs once.
It's as though the AddHandler actually forces the event to run when it's
created.
I have never been able to ge the Save or Cancel events to fire under any
circumstance.
Another issue I have found: if you click on the edit button for the first
item in the grid, it goes into edit mode. If you then click on the edit
button for the second item in the list it wil go into edit mode. Then, if
you go back to the first item and click on Edit, it will not go into edit
mode (edit mode stays on the second line).
I originally thought this was due to viewstate for the dg, but even
disabling it did not work.
Thanks,
MM

It took a little while of playing to get it to work, but as it turns out all I did was move the Call BindData() statement which is in the Page_Init
sub so that it is below the call to: InitializeCompo nent
(I should have seen it without recreating everything!)
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form Designer
'Do not modify it using the code editor.
InitializeCompo nent()
Call BindData()
End Sub
Sincerely,
