Sending values to action - the correct way

Hi,

please have a look at my forum post:
http://www.kendoui.com/forums/permalink/boGRRa6aG2OF1P8AAFTdxQ

I posted it in the wrong category. Its actually ASP.NET MVC 4! If somebody could move it to this forum, that would be great.

Regards,
Marcus

Post filtered grid's results back to server

Hi

How can I go about posting the grid back to my controller with the filtered results?

I basically have a filterable grid and a button which need to handle the data from the grid, but only the filtered results using the built-in filtering functions.

Thanks

Creating a custom edit form

The edit functionality of the grid is not working out for me...
I have come up with an ajax action link but would like to style it the same as the edit button without it firing the edit.

so far I have this but it produces one icon in the button and one outside of the button and there is no text, How can I recreate the edit button without it firing the default edit command of the grid?

<a class='k-button k-button-icontext' data-ajax='true' data-ajax-mode='replace' data-ajax-method='Get' data-ajax-update='\\#editorform' href='/FallsAssessment/Edit?EventID=#=EventID #' data-ajax-success='showModal'><span class='k-icon k-i-pencil'/>Edit</a>

Thanks

David

"The method or operation is not implemented" with 2013.1.319.340

Hi,

Just downloaded 2013.1.319.340 and am receiving the following error when using the menu:

"The method or operation is not implemented".

(StackTrace)

[NotImplementedException: The method or operation is not implemented.]

(rest omitted for brevity)

The code is as follows:

@(Html.Kendo().Menu()

.Name("mn-case")

.Items(items =>

{

items.Add().Text("Dashboard").Action("Index", "Dashboard", new { caseId = caseId, area="Case" });

}))

The route is defined as follows:

context.MapRoute("CaseIndex",

"Case/{caseId}/{controller}",

new { action = "Index"},

new RouteValueDictionary { { "httpMethod", new HttpMethodConstraint("GET") }}

);

This did not happen in previous versions and the workaround is to use Url.Action as follows:

items.Add().Text("Dashboard").Url(@Url.Action("Index", "Dashboard", new { caseId = caseId, area="Case" }));

I have many projects that use the menu and do not want to have to change them all. Is this a problem on my end or is it Kendo?

Thank you,
David Adams

[Solved] Panel bar data object is null in initialization

Hello,

I'm trying to migrate a panel bar from MVC extensions to Kendo. When the Panel bar loads, I expand specific items via a initialization script.
What I find is that if I call

var panelbar = $("#PanelBar").data("kendoPanelBar");

in $(document).ready() as adviced as in

http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/migration/widgets/panelbar, I get a null object.
This call however succeeds to get the correct object if called later.
Since, onLoad() is removed in Kendo, is there any other way I can initialize my Panelbar ?

Kind Regards

Achilles

change event column exclusions

I have a grid with a change event. When the change event is invoked a redirect takes place towards another page.
I want to add a column with a checkbox which does not cause the change event to be fired. The other columns must still cause the change event to be fired.
How can this be done?

The same is valid for the listview. I have a listview with a client template and I need to show a checkbox which doesn't cause the change event to be fired.

[Solved] Expand and Select Node with ID in TreeView

Hi,

I'm almost done with the code from the subject. The tree expands already to the given ID, but unfortunately it does not select the node given by ID

Edit: Just to clarify, because I read a few threads regarding this issue - I don't get any error messages nor do I get 'undefined' for any variables. The node just doesn't get selected.

function expandAndSelectNode(id, treeViewName) {

// get the Kendo TreeView widget by it's ID given by treeviewName

var treeView = $(treeViewName).data('kendoTreeView');

// find node with data-id = id

var item = $(treeViewName).find("li[data-id='" + id + "']").find(".k-in");

// expand all parent nodes

$(item).parentsUntil('.k-treeview').filter('.k-item').each(

function (index, element) {

$(treeViewName).data('kendoTreeView').expand($(this));

}

);

// get DataSourceItem by given id

var nodeDataItem = treeView.dataSource.get(id);

//get node within treeview widget by uid

var node = treeView.findByUid(nodeDataItem.uid);

$(treeView).select(node);

//treeView.select(".k-item:last");

}

I also tried $(treeView).select(item), since it should already point to the <span> item I want to select anyway. This didn't work.
Then I tried tried $(treeView).select(item.closest('.k-item')), since it points to the parent <li> element, but this didn't work either.
The uncommented line (treeView.select(".k-item:last")) was just for testing and works.

I'm a little bit stuck and glad about any hints.

Self-Referential Foreign Key field in Grid

I have a grid for a model Departments. Departments has a foreign key field ParentDepartmentKey. The foreign key field correctly generates a dropdown list with Departmens listed. However, if you add a new department, it is added to the grid, but the dropdown in the foreign key field is not updated and does not update.

Is it possible to have the foreign key field update when an item is added to the grid?
