Grid Batch Mode - Add new row programaticlly

Having a bit of an issue adding a row via javascript to an ajax bound grid where the data source is set to batch mode.

While the edit and deletes are working fine, when i add a new record via javascript it appears to have worked, as in the row appears in the grid, but when save is clicked the create action for the new rows is never activated.

I presume it's because when the row is added directly to the data source there is no flag to indicate it's "dirty" so that it's marked for saving when save is evoked but cannot find anything in the API to flag a row like this. Nor can i find a way for adding a row with data to grid direct

@(Html.Kendo().Grid<UserViewModel>()

.Name("Grid")

.ToolBar(toolbar => {toolbar.Save(); })

.Editable(editable => editable.Mode(GridEditMode.InCell))

.Sortable()

.Pageable(pager => pager.PageSizes(true))

.Selectable()

.Columns(columns =>

{

columns.Bound(c => c.DisplayName);

columns.Bound(p => p.Attended)

.Title("Attended")

.ClientTemplate("<input type='checkbox' #= Attended ? checked='checked': '' # class='chkbx' />")

.HtmlAttributes(new { style = "text-align: center" }).Width(50);

columns.Bound(c => c.Duration).Width(100);

columns.Command(commands => commands.Destroy()).Width(100).Title("Remove");

})

.DataSource(dataSource => dataSource.Ajax()

.Model(model =>

{

model.Id(p => p.ServiceUserID);

model.Field(p => p.DisplayName).Editable(false);

})

.ServerOperation(false)

.Read(read => read.Action("_GetAttendees", "Activity", new { ViewBag.ActivityID }))

.Create(update => update.Action("_AddAttendees", "Activity"))

.Update(update => update.Action("_UpdateAttendees", "Activity"))

.Destroy(update => update.Action("_RemoveAttendees", "Activity"))

.Batch(true)

.PageSize(20)

)

function AddUser(searchModel) {

$.getJSON("/Activity/GetUser", searchModel,

function(data) {

switch (data.Value) {

case 0:

<snip>

break;

case -1:

<snip>

break;

default:

var grid = $("#Grid").data("kendoGrid");

var datasource = grid.dataSource;

var activityID = @ViewBag.ActivityID;

var User = { UserID: data.Value, ActivityID: activityID, DisplayName: data.Message, Attended: 0 @ViewBag.Duration };

datasource.insert(User);

break;

}

return false;

});

};

Treeview loaded from remote data source will not expand

Help! I have NO idea what I'm doing wrong! The initial node loads and shows an expand icon but nothing happens when it's clicked. No request is even attempted. I have the following code:

var homogeneous = new kendo.data.HierarchicalDataSource({

transport: {

read: {

url: 'http://localhost:500/api/users/',

dataType: "json"

}

},

schema: {

model: {

id: "id",

hasChildren: "load_on_demand"

}

});

$("#tree").kendoTreeView({

dataSource: homogeneous,

dataTextField: "label"

});

The 'http://localhost:500/api/users/' is an ASP.NET Web API controller method that returns the following JSON:

[{"id":12345,

"label":"NODE 1",

"load_on_demand":true

}]

What am I doing wrong? Any ideas would help!

ListView data is null when dataBound event fires

$(document).ready(function () {

$("#listView").kendoListView({

dataBound: function (e) {

var listView = $("#listview");

if (!listView) {

alert("listView null");

return;

}

var listData = listView.data("kendoListView");

if (!listData) {

alert("listData null");

return;

}

});

The above code shows "listData null". I need to access .data() and thought the purpose of the dataBound() event was to indicate when I could do so. What event should I use if not this one?

Thanks,
David

EDIT: I'm sorry, it was my mistake. I should have typed "listView" instead of "listview". After this change, I can access .data() from the dataBound() event handler.

Header Wrapping / Height

I have a grid that is dynamically driven by metadata with the user choosing the columns they want to see. I do not know ahead of time what the headers will be or how many columns the user will select. I have the grid setup with a fixed height and every column gets a fixed width of 200. What happens is that some columns header is bigger than the allowed space and gets cut off. Is there any way to increase the height of the header and have the text wrap to a new line? Any other solutions for this?

[Solved] Call function AFTER menu effect has completed

I have a menu that is contained in a slide-in div (using kendo.fx.slidein) and I want to make sure the slidein effect does not play until *after* the menu effect has completed.

Is there a way to ensure that my KendoMenu close event is called after the animation is complete, or to have the close event function handler call the slidein effect asynchronously with the menu effect?

Thanks.

Bind column to a computed prperty

I have a grid with several computed columns.I set the computed properties when I change the properties in the grid edit mode . Do I need to use editor template to make a read only column (when I set editable:false it doesn't change according to the new value)?

And I have several computed properties in grid, Is there any other way to make it a generic calculation instead of using if/else for change property name like this,

save: function(data) {

if (data.values.Qty) {
var test = data.model.set("Total", data.values.Qty * data.model.Amt);
}
else {
var test = data.model.set("Total", data.model.Qty * data.values.Amt);
}
}

Is there any event like saved (to get the data.model with changed property has been set)?

And the other issue is when I have several computed fields set like this the save method is called for each calculated field set.

Here is my example,

Request: BeforeDragStart Event

Is it possible to get a BeforeDragStart event? I need to handle some things before the "hint" is created and I need access to whether ctrl/alt/shift is pressed (which isn't available in the hint function). Thanks!
