Questions on Kendo UI for jQuery Forum

if I bind to a nullable integer which has an initial value of null, the combobox always returns a null value value to the controller, even if a value has been selected. if I change it to work with a standard integer, it returns the correct value, but it also sets an initial value in the list which I do not want.

thoughts?

no initial value, but not updating either: public int? QuoteId { get; set; }
returning values as expected, but populating 0: public int QuoteId { get; set; }

@(Html.Kendo().ComboBoxFor(m => m.QuoteId)
.DataSource(dataSource => dataSource
.Read(read => read.Action("GetQuoteList", "Payment")))
.DataTextField("Text")
.DataValueField("Value")
)

Record Count is not correct when ServerOperation=false

Hi,

I have a similar code as your sample (http://demos.kendoui.com/web/grid/editing.html)

@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.ProductViewModel>()
    .Name("Grid")
    .Columns(columns => {
        columns.Bound(p => p.ProductName);
        columns.Bound(p => p.UnitPrice).Width(140);
        columns.Bound(p => p.UnitsInStock).Width(140);
        columns.Bound(p => p.Discontinued).Width(100);
        columns.Command(command => command.Destroy()).Width(110);
    })
    .ToolBar(toolbar => {
        toolbar.Create();
        toolbar.Save();
    })
    .Editable(editable => editable.Mode(GridEditMode.InCell))
    .Pageable()
    .Sortable()
    .Scrollable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .Batch(true)
        .ServerOperation(false)
        .Events(events => events.Error("error_handler"))
        .Model(model => model.Id(p => p.ProductID))
        .Create("Editing_Create", "Grid")
        .Read("Editing_Read", "Grid")
        .Update("Editing_Update", "Grid")
        .Destroy("Editing_Destroy", "Grid")
    )
)
When I tried to add a new record, the count is incremented (say from 6 to 7), but once I hit the Save button, the count goes back to 6. If I refresh the page, the count will be correct (7). Any idea on how to fix this? Thank you so much.

Bug in Online Demo (related to Nextflix)

The ComboBox binding to remote data demo is broken. When it tries to bind the combobox, it throws the error "Uncaught SyntaxError: Unexpected token > ". This happens in both Chrome 26 and IE8.

I tried to submit a bug report about this, but kept getting server errors when I tried to submit.

Set a Layout to a View in Javascript

I have this situation:

I have some Views and by default they have assigned a Layout for them. The problem is that in some specific cases, I need to change the Layout of some of these Views in the Javascript file.

I am using this way:

$("#tabstrip-dash").setAttribute('data-layout', 'mobile-tabstrip-layout2');

This solution works only if I reload the application, but I want to change it instantly.

Is there any way to set the new Layout?

Thanks!

Bubble Chart x-axis buffer

Hi All,

Just wondering if there is an out of the box solution for my small but frustrating issue:

I am plotting bubbles on a chart, that has a y-axis of, say, min 0 and max 200. If I plot a bubble at y-0 the bubble will naturally cover the x-axis, which is correct. However, the way my chart has been designed (drop shadow involved!), I do not want the bubble to cover the x-axis line, I need some sort of buffering so min y-axis value appears higher up, therefore the whole bubble can fit into the chart, within the x-axis.

Any advice would be appreciated!

Cheers
Chris

Trying to get batch edit to affect more than one value

So I have a scenario which I believe should be do-able in some form however I can't seem to figure out how to do it. Take for example the batch editing on the demo page: Batch Demo

Now imagine I've added another column which is now "Total Cost". What I'd like to do is trap on either a change in "Unit Price", or change in "Unit Stock" and be able to update the "Total Cost" field, and mark that as dirty.

I can go into the datasource and alter the value, but it seems when I refresh the grid, the dirty statuses are cleared. Is there a nicer way to do this that I'm missing?

Demo of Batch Editing with Enum Columns?

I'm just evaluating the Kendo grid for an upcoming project and I'm hunting for demos for the functionality that I need.

I have created a grid in an asp.net razor view that takes a viewmodel. A couple of the model properties are enums which display nicely but when clicking into the cell just render a text box with the enum value (1,2,3,etc).

Does anyone have a demo where the edit field is an appropriate dropdown rather than the raw value of the enum?

Thanks in advance :)

=================================================================================

For reference the model and view I'm using are:

public class HomeMonitorViewModel {

public int Id { get; set; }

[Required, StringLength(255)]

public string Name { get; set; }

[Required, StringLength(128)]

public string HostSystem { get; set; }

public string Description { get; set; }

public Data.MonitorClassification Classification { get; set; }

public DateTime DateAdded { get; set; }

public bool HasBeenAdministered { get; set; }

public Data.MonitorSource Source { get; set; }

public int MonitorAliasId { get; set; }

public string MonitorAliasName { get; set; }

}

public enum MonitorClassification {

Default = 1,

Standard = 2,

Bespoke = 3

}

public enum MonitorSource {

Policy = 1,

Adhoc = 2,

Unknown = 3

}

@(Html.Kendo().Grid<ProjectBlackSun.Models.Home.HomeMonitorViewModel>()

.Name("MonitorGrid")

.Columns(c => {

c.Bound(m => m.Name);

c.Bound(m=>m.MonitorAliasName);

c.Bound(m=>m.Description);

c.Bound(m=>m.HostSystem);

c.Bound(m=>m.Classification);

c.Bound(m=>m.Source);

})

.ToolBar(t => {

t.Create();

t.Save();

})

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

.Pageable()

.Sortable()

.DataSource(d => d

.Ajax()

.Batch(true)

.ServerOperation(false)

.Events(e => e.Error("error_handler"))

.Model(model => model.Id(monitor => monitor.Id))

.Create("MonitorGridCreate", "Home")

.Read("MonitorGridRead", "Home")

.Update("MonitorGridUpdate", "Home")

.Destroy("MonitorGridDestroy", "Home")

)

<script type="text/javascript">

function error_handler(e) {

if (e.errors) {

var message = "Errors:\n";

$.each(e.errors, function (key, value) {

if ('errors' in value) {

$.each(value.errors, function() {

message += this + "\n";

});

}

});

alert(message);

}

</script>

Setting new datasource for editable grid not working

Hello,

I have added an example of the problem, see:
http://jsbin.com/edamuj/427/edit

I have an editable grid and want to connect it with an editable datasource. This works if I create the grid with the datasouce available. However in my solution I am not sure when the js for the datasource is rendered but if it is rendered I register it in a kendo observable array. A function to set the the grids datasource is bound the change event of the observable array. After this function fires I would like the grid to show the data. Unfortunately this is not working. I simplified the problem and added it as an example. Can someone explain to me what I am doing wrong here?
