Passing current DropDown as parameter

I have a EditorTemplate which is:

@model string

@(this.Html.Kendo().DropDownList()

.Name(this.ViewData.TemplateInfo.GetFullHtmlFieldName(string.Empty))

.Value(this.Model)

.HtmlAttributes(new { style = "width: 220px;"})

.OptionLabel("Select)

.DataValueField("Value")

.DataTextField("Text")

.DataSource(ds => ds.Read(read => read.Action("GetList", "Combo").Data("getAdditionalParam")))

)

I want to get this dropdown in my function:

function getAdditionalParam(dropDown){

//do stuff with dropDown

//

return { additionParam: 1 }

}

Is there anyway to pass the object itself as parameter?

Thanks,

Ezequiel

ForeignKey columns with parent / child relationship

I have a grid with multiple ForeignKey columns which work nicely however i'd like to be able to set up some column dependencies.

Is the above possible to have a child ForeignKey column either updated or filtered based on the selected value of the parent ForeignKey column?

Ideally i'd like to call an action on change as the initial data is generated in the controller.

So far I've not been able to find an example that does all of the above.

Thanks

Graeme

Tile Layer using Layer from Web Map Server (WMS)

Hello,

Is it possible to format the urlTemplate in such a way that we can connect a layer of type Tile to a Web Mapping Server?

The problem seems to be fulfilling the BBOX parameter that the WMS Standard expects.

If not, could you please suggest a suitable work-around one can implement to get the Layers from a WMS integrated?

Regards,

Aaron

Manual async upload?

Hi! I'm wondering how one can upload asynchronously given the following:

-- Auto upload is false

-- User clicks an upload button to initiate the upload via ajax WITHOUT doing a form post.

Thanks!

Select all users for the meeting

Is there a way to "Select All" users in the editor popup?

I'm using .AutoClose(false), but that's not enough for the client. They want to select all users.

I'm using editable.TemplateName("CustomEditorTemplate");

Timepicker

Hi,

I want to edit and display in a kendo window a time property (format HH:mm).
I started with the Time editor and with a DateTime attribute, but the value to be biended is not displayed in the form.
How can we fix it ?
Apparently the Timepicker supports a TimeSpan value, but Javascript doesn't support Timespan (json serialization problems).
ex : @Html.EditorFor(m => m.StartTime, "Time")

Thanks for your help

Custom Button on TreeList - no action

I'm trying to add a custom button on a TreeList Toolbar. I can see that .Toolbar (t=>t.Custom().Text("My Action")) is exactly what I'm looking for, however what is not obvious is how to add the action. For the Grid, it would be .Toolbar(t=>t.Custom().Action("Action", "Controller").Text("My Action"). Why does TreeList have similiar behaviour?
