[Solved] Commands.Delete() Only?

[TonyRasa]

Hi,

I have a Grid using Ajax data binding, and I want to have a Delete Command button (and ONLY a delete command).  But, if I don't add in an Edit command and fully implement the required bindings, then none of the command buttons render (I just get an empty td where the buttons should be).

Is there some trick I'm missing to have a Delete button without also enabling edit functionality?

Thanks
Tony

Hello TonyRasa,

This is a known issue and I am glad to inform you that it is already fixed. The fix will be included in our next release.

Currently the workaround to use only Delete command is to set Editable(settings => settings.Enabled(true).
Here is a code snippet showing what I mean:

...
.Columns(columns =>
{
   ...
   columns.Command(commands => commands.Delete())
})
.Editable(settings => settings.Enabled(true)
...

I had the similar issue and setting the editable settings fixed it. Thanks.

Hi,

I tried this and it worked fine for display mode, but when I tried to insert a record there were no command buttons rendered, and so I could not insert the record.

My grid definition is:

<%= Html.Telerik().Grid(Model)

        .Name("TestGrid")

        .ToolBar(commands => commands.Insert())

        .DataKeys(keys => keys.Add(c => c.TimeLogged).RouteKey("time"))

        .DataBinding(dataBinding => dataBinding

            .Server()

            .Insert("Insert", "TestEntry")

            .Update("Update", "TestEntry")

            .Delete("Delete", "TestEntry"))

        .Columns(columns =>

        {

            columns.Bound(c => c.TimeLogged).Width(200).Visible(false);

            columns.Bound(c => c.Weight).Width(200).Format("{0:N3}");

            columns.Bound(c => c.Location).Width(250);

            columns.Bound(c => c.Reason).Width(200);

            columns.Bound(c => c.Description).Width(200);

            columns.Command(commands =>

            {

                commands.Delete();

            }).Width(200);

        })

        .Editable(settings => settings.Enabled(true))

        .Pageable()

        .Sortable()

        

%>

Actually I'd like to achieve being able to insert a record without any other command button in display mode. Is there any way to do this?

Thanks,

Col.

I'd like to second Colin's question. I am trying to get Insert functionality to work in my grid but there are no command buttons rendered (the input fields are rendered just fine). I have tried using Inline as well as PopUp, to no avail.

What could cause this? My code is as follows (using version 2010.2.825):

<%: Html.Telerik().Grid(Model.Accounts)
          .Name("Acccounts")
          .ToolBar(commands => commands.Insert())
          .DataKeys( keys => keys.Add( a => a.Email))
          .DataBinding(binding =>
            binding.Ajax()
                    .Insert( "AddAccount", "Company" ))
          .Columns(columns =>
            {
              columns.Bound(a => a.ContactName);
              columns.Bound(a => a.MobileNumber);
              columns.Bound(a => a.Email);
              columns.Bound(a => a.IMEI);
              columns.Bound(a => a.SipAccount.Username);
            })
          .Editable(editing => editing.Enabled(true).Mode( GridEditMode.PopUp ))
          .Footer(false)
%>

Hi Erik,

There is a known issue with insert only grids. We have fixed it so it works as expected in InForms and PopUp editing mode. We have still not enabled it for inline mode as we are not sure where the render the "insert" and "cancel" buttons if there is no command column in the grid.

If you are interested you can open a support ticket and I will send you the updated build which enables "insert-only" popup or informs editing.

Hi Atanas,

Thanks for you lightning-quick response. I will create a support ticket for this as you suggest.

Best Regards,

Erik

Ah, I seem to have hit Reply too soon.

Hi Anatas,

I am not allowed to create support tickets as I am using the open source edition of the MVC Extensions. Is there any other way I can get the build you mentioned?

Regards,

Erik

Hello Erik,

I am sending you the internal build so you can try it.

Hi Atanas,

Perfect! The buttons show up just fine in both PopUp and InForm mode. Thanks!

As a mini feature-request, could I suggest wrapping said buttons in a DIV element with a class (e.g. t-edit-form-buttons)? This would allow us to assign styles to it more easily than going through the t-edit-form-container t-grid-action t-button hierarchy.

Thanks very much for you help, also on behalf of my customer :)

Hi Atanas,

Once again thanks for your help, everything now works like a dream!

In one of your replies you said:

"We have still not enabled it for inline mode as we are not sure where the render the "insert" and "cancel" buttons if there is no command column in the grid."

Would it be a good suggestion to replace the "Add new record" button in the Toolbar with those two ("Insert" and "Delete") buttons? The "Add new record" button has no functionality when you are inserting a new record (clicking it does nothing and you hsouldn't want to insert another record while not finished inserting the first) so replacing this would make the intent perfectly clear from a user's perspective.

Just my 2c :)

We're also trying to have an Insert-only grid. 

We are on the current release, 2010.2.825, but the PopUp & InForms mode do not include the Insert/Cancel buttons unless I add an Edit command column.  We are currently working around this by setting that column to Hidden, but is there a better fix for this?

We are using server binding, does that make a difference?

[Erik]

Hi H,

I don't think using server binding makes a difference. I'd suggest downloading the hotfix out of the previous post and trying that, it solved the problem for me (and without breaking anything, which is a nice bonus ;)
