PageControl - Why does a callback performs the POST action

Hello Tarek,

All callbacks are asynchronous queries that are sent via POST requests. That is why your code raises post actions.
You mentioned that Html.Partial does not work fine for PageControl. Would you please illustrate the issue with a small sample? I need to know how you are using our extensions to get a blank page instead of a proper tab.

Thanks,
Vest

Hello Vest,

Thank you for your quick reply. Please find attached a small sample to illustrate what we are trying to accomplish.

Actually, we are starting a new ASP.NET MVC project and we wanted it to be a full DevExpress ASP.NET MVC project and that's what we chose on Visual Studio 2010 from the projects list.

In fact, we would like to use only callbacks for improved performance and better look & feel. The problem is that we are trying to figure
out how we can manage different callbacks (tab click, button, GridView Binding, GridView paging, Callback Panel, etc.) within the same view and associated to the same controller.

For instance, we have a "Details" tab that fires a callback after which its content is loaded. This content contains a ComboBox which is also populated during the rendering of the other controls, then we also have a submit button that fires a callback after which a create method is executed to add a new client. By the way, how can the callback be activated on a button?

Thank you in advance

Hello Tarek:

Thank you for the sample. We need time to test it and find an appropriate solution, so please accept our apologies for the delay in responding.
We will keep you informed of any progress.

Thanks
Kate.

Hi Tarek,

Unfortunately, we could not start your project, because we do not have some sample data. But we have reviewed the sample that demonstrates your scenario.
If you use our control that supports callbacks, you need to use separate Partial View with this extension. This way, conflicts between different callbacks of MVC extensions don't occur. If you want to perform a callback by clicking on a button, call the client function such as tabControl.PerformCallback().

Hi Maxim,

Apparently my question was not clear.

Anyway, is it possible to navigate through a PageControl tabs by adding URL parameters (?action=edit&id=5) ?
In that case, I am not sure it is a good idea to have the action being part of the URL parameters. For instance I have a partial view associate to one tab, and this same partial is used for both actions create (add new entry) and edit (update an existing entry). From a MVC best practise point of view, is it better to have different partial view for each action and both views are loaded within the same tab depending on the requested action?

What is the best way to accomplish this task.

Thank you in advance,

Hello Tarek,

Thank you for your reply.
We need time to review the issue in light of your clarification. We will contact you once we have any results.

Best regards,
