Dynamically created dynamic grids not refreshing

Hi,

I have a requirement for users to be able to select and add grids to a page without knowing the table schema beforehand.

I have a partial view to display a grid from any given data table using initial Server Binding with Ajax updates. When adding several of these grids to a view using Html.Action they work as expected.

However, when I add the above grids dynamically using an Ajax.BeginForm request the grids initially display correctly but any refreshes or page changes causes an error. The dynamically added grids are rendered differently (eg. missing data-role="grid") and they send HTTP GET requests instead of HTTP POST.

I've attached the Controller and Views I'm using for testing.

Grid Failing with Mono (GridEditMode.PopUp )

I have asked this question on Stackoverflow and got no answer. So hopefully I can get a bit more help in this forum.

When I add the following line to my Grid declaration:

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

I get the following error:

System.IO.FileNotFoundException

Could not load file or assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

This error goes away when I do not try and edit via PopUp.

Mono does not support `System.Data.Entity`, and because of this there is no where in my solution where I register that.

There is also no reference to that library in my `web.conf` file.

Can someone please help me resolve this problem?

Icons on TreeView Node

I am using Method 2 for binding my data to a flat file as shown here:
Binding to a Flat Table

<div id="tree"></div>

<script>

var flatData = [

{ id: 1, parent: null, text: "Item 1" },

{ id: 2, parent: null, text: "Item 2" },

{ id: 3, parent: null, text: "Item 3" },

{ id: 4, parent: null, text: "Item 4" },

{ id: 5, parent: 1, text: "Item 1.1" },

{ id: 6, parent: 1, text: "Item 1.2" },

{ id: 7, parent: 1, text: "Item 1.3" },

{ id: 8, parent: 3, text: "Item 3.1" },

{ id: 9, parent: 3, text: "Item 3.2" },

{ id: 10, parent: 5, text: "Item 1.1.1" },

{ id: 11, parent: 5, text: "Item 1.1.2" },

{ id: 12, parent: 5, text: "Item 1.1.3" }

];

// tree for visualizing data

$("#tree").kendoTreeView({

dataSource: {

transport: {

read: function(options) {

var id = options.data.id || null;

options.success($.grep(flatData, function(x) {

return x.parent == id;

}));

}

},

schema: {

model: {

id: "id",

hasChildren: function(x) {

var id = x.id;

for (var i = 0; i < flatData.length; i++) {

if (flatData[i].parent == id) {

return true;

}

return false;

}

})

</script>

Now, however, I need to add some icons to differentiate the kind of file (Folder, excel, PDF, etc)

I have found a series of icons that I think would work would work at:
jQuery icons styling example
I just am not sure how to add the desired icons (or their references) into the JSON or set the TreeView up to show them.

What I have found only shows how to hard code the data and the associated images. I need to get this all into the JSON for my app.

I have tried adding another JSON field called "image", but that does not seem to work.

So, how would I set it up and show it?

TIA,
Bob Mathis

Combo box -Loading 4000 records

Currently we are using the kendo combo control to load values in one of the screen in the application. The problem is that the combo takes time to load the
values are there are around 4000 records to load.

1. Is it a problem to load 4000 records in the combo control?
2. Given this scenario, we would like to have pagination as part of combo where we would able to load say 50 records per page and then navigate between pages to fetch the subsequent records.

Let us know if it would be possible to build such a custom template.

Appreciate your help.

ColumnMenu how to show applied filter

How can I highlight that a filter has been applied to a column after I enable the option to choose columns using .ColumnMenu()

Refer to the attached screen shots No ColumnMenu Filter.png and No ColumnMenu Filter Applied.png when I don't have the .ColumnMenu() applied a user can visually see that a filter has been applied.

Below is the MVC Helper config for completeness:

@(Html.Kendo().Grid(Model)

.Name("Grid")

.Columns(columns =>

{

columns.Bound(f => f.FluidID).Width(50).Title("ID").Hidden();

columns.Bound(f => f.Name).Width(150).Title("Name");

columns.Bound(f => f.Code).Width(150).Title("Code");

columns.Bound(f => f.Grade).Width(150).Title("Grade");

columns.Bound(f => f.Manufacturer).Width(150).Title("Manufacturer");

})

.Deferred()

.Resizable(resize => resize.Columns(true))

.Reorderable(reorder => reorder.Columns(true))

.Groupable()

.Pageable()

.Sortable()

//.ColumnMenu() <-- Once enabled, there is no visual cues to highlight that a filter is applied

.Scrollable(s => s.Height("auto"))

.Navigatable()

.Filterable()

.Events(e => e

.DataBound("grid_dataBound")

)

.DataSource(dataSource => dataSource

.Ajax()

.ServerOperation(true)

.Read(read => read.Action("GetJsonData", "FluidKendo"))

)

Once I enable .ColumnMenu() the filtering options are contained in a submenu item and the user is unable to visually see if a column filter has been applied. Refer to ColumnMenu.png and ColumnMenu Filter Applied.png.

I want users to be able to choose columns and highlight when filtering is applied to columns. Is there any way I can achieve this?

Is there any other way I can enable grid column selection without enabling .ColumnMenu(). I have tried: http://stackoverflow.com/questions/13637475/how-to-show-kendo-grids-columnmenu-using-script but the grid .ColumnMenu() option needs to be enabled for this to work which defeats the purpose.

Maybe there is an options to show as text, what filter options have been applied, hook into an event?

Thanks,
Beau

Object doesn't support property or method 'slice'

I am attempting to implement a Kendo DropDownList with server filtering. I have the following in my view (.cshtml):

@(Html.Kendo().DropDownList()

.Name("UnselectedADGroups")

.DataTextField("Name")

.DataValueField("Name")

.Filter("StartsWith")

.DataSource(source =>

{

source.Read(read =>

{

read.Action("GetUnselectedADGroups", "ARItemPost");

}

)

.ServerFiltering(true);

})

)

I have the following in my controller:

public ActionResult GetUnselectedADGroups([DataSourceRequest]DataSourceRequest request, string startsWith)

{

try

{

var groups = ARItemPost.GetUnselectedADGroups(startsWith);

var result = groups.ToDataSourceResult(request);

return Json(result, JsonRequestBehavior.AllowGet);

}

catch (Exception e)

{

ErrorSignal.FromCurrentContext().Raise(e);

return null;

}

I have verified that I'm getting results back from the AJAX call (it's a collection of a simple object with a single public string property called "Name"), but the dropdown list does not populate and I get an "Object doesn't support property or method 'slice'" error on the "i_pristineData=n.slice(0);" line of [I think] kendo.all.min.js.
