I know there is plenty of posts with the UpdateCommand not firing, but I am at a loss why these event(s) do not get called after clicking on the update link in the grid. My grid is dynamically built, and once running, it has all the features that I requre, however, when clicking on the edit link the approriate event gets called, so far so good, but when I click on the update link none of these events fire.
I handle NeedDataSource and I have tried various combinations of viewstate but to no avail.
Can you advise, thanks

You should not create the grid in NeedDataSource event handler. Please visit these examples for more info:

I did not create the grid in the NeedDataSource event handler I created the grid in the Page Init, please view supplied code
Thanks

Sorry for this miscommunication. Can you send us via support ticket small example which demonstrates this behavior? I will gladly help you.

The application is very big, and it will take me some considerable time to strip it down to give to you as an example. I thought you would might spot something obvious or give me some pointers.
The grid I have created dynamically works fine in every respect, this includes custom templated colums for the header, Item and Edit, simply, the grid does not receive the ‘update’ event after an edit.

Where is your code for updates held? In this case, I think there needs to be a call in the ItemCoimmand method that determines the type of event. From there, pass off to the Update, Delete, etc..
You didn't define the handlers in the code given, but if your code is in the itemupdated, it woun't reach it. The grid only knows that you clicked a button in the EditCommandColumn; it doesn't know WHAT happened until it enters the ItemCommand event handler.
Also, do you need to explicitly declare AllowAutomaticUpdates? I know that they deal with object datasources, but perhaps setting them False is causing an issue?
Thanks for listening.

Thanks Sean for your time, I really appreciate it.
In the code supplied, I do hook up to the ItemCommand Event, I have also tried various combinations of setting the AllowAutomaticUpdates and the viewstate, but still, this event does not get fired on an update click.
The ItemCommand Event does fire on an edit click but not on a update click, I am still at a loss why this event does not fire.
Thanks

Can you verify that you instantiate your grid programmatically in par with the concepts listed in this article from the documentation? Additionally, verify that you use advanced binding with NeedDataSource handling as explained here.
The information provided so far is not sufficient to pinpoint the source of the problem, therefore the best means to progress in our investigation is to send a stripped working version of your project, exhibiting the issue, attached to formal ticket. We will test it locally and will advice you further.

If I send you a stripped down project, what does entail? My project is run over the ADO Entity Framework. I suppose I will have to send you the model and the DB.
However, may I suggest an easier alternative:- Can you send me a simple dynamic grid which demonstrates the edit and Update event in action
Thanks P
You will find the requested example attached to this forum post. Note that using a different data layer should not make a difference as long as you assign the data source returned from the DAL inside the NeedDataSource handler of the grid.

Thank you for your time I really appreciate the attentiveness.
The sample that you sent me , does not compile. I managed to compile the app by adding a RadScriptManager to the designer surface, then from its context sensitive menu add the WebResource.axd
That Done....
When the app was running, I edited a value (contact name), then clicked the update button, the Update did not take place, the value was unchanged.
This is exactly the same behaviour that I am experiencing (why I raised this issue)
mmm….
I am using Visual Studio 2008 SP1, .NET Framework SP1. The app that you sent me is not at this version.
Do you want me to send you the demo app that you gave me re-configured for this environment.
Hope this Helps

The actual update operation is not implemented in the example, however if you attach the UpdateCommand/ItemCommand events of the grid they should be raised when you click the update button.
Can you please verify that on your machine? If you would like to implement manual data editing for your grid control, review the following online demos which demonstrate possible approaches:
http://demos.telerik.com/ASPNET/Prometheus/Grid/Examples/DataEditing/EditModes/DefaultCS.aspx

I have not been able to get my update event to fire, but what I have noticed between your demo app and my app is the order of events
Your App :
ItemCommand -> NeedDataSource
My App
NeedDataSource -> ItemCommand
for both Edit and Update click.
Does this makes any difference?
P
Rank 1
Should read
Your App :
ItemCommand -> NeedDataSource
My App
NeedDataSource -> ItemCommand
for the Edit click.
Does this makes any difference?
The proper sequence of events raised should be:
ItemCommand -> NeedDataSource
as listed in this topic from the online documentation. Is it possible that by some reason you disabled the viewstate for your grid instance? This might be the reason for the unexpected behavior you observed.

I do not turn off the viewstate for the dynamic grid, and just to make sure I have expliticly Enabled the viewstate

grdBaseListMembers.EnableViewState =

grdBaseListMembers.Skin =

grdBaseListMembers.MasterTableView.Width = Unit.Percentage(100)
grdBaseListMembers.MasterTableView.DataKeyNames =

I am running out of ideas here. To progress in our investigation, can you modify the sample project I prepared for you in order to make the abnormality surface and send it back attached in a standard support ticket? Thus I will do my best to advice you further/provide a solution for your case.

I have manged to get th update click to work along with the correct order of events (but unfortunatly I do not know why)
I have moved the placeholder where my (dynamic grid resides) from one part of the page to another location. The PlaceHolder was in a RadPane and I moved it to a RadSlidingPane, both of these panes are in a RadSplitter,
And it all burst into life...

I ran into somewhat of the same issue, I was setting up a grid in a control used in another control. The grid is within a RadPanel, same issue, no OnUpdateCommand event, although the OnDeleteCommand works.

I think the radGrid has some sort of issues with this layout configuration. I have tried all of the telerik recommendations regarding the 'dynamic grid', but to no avail. I am going to have to redesign my web page so I can get the functionality I require .i.e. Sinking the ItemCommand 'Update' event.
