Hi,

I have a simple page with a droplist and a chart. When selecting an item of the droplist, I update the chart with new values. The new chart can have different number of categories. On initial load the chart displays correctly with all the categories legend. When selecting a different element from the droplist, the chart updates correctly but the categories legend does not.

For example, if the original chart had 5 categories and the selected item has 4, the chart still shows 5 categories where the 5th category is empty (no graph) but the 5th category legend still shows. Whereas if the selected category has more series then the original, the chart displays correctly the additional categories but the the category legend is blank. Somehow the category legend does not change.

Using kendo version 2013.1.514.

Manufacturers @(Html.Kendo().DropDownListFor(m => m.MfgList)

.Name("mfgList")

.DataTextField("Text")

.DataValueField("Value")

.BindTo(Model.MfgList)

.HtmlAttributes(new { style = "width:200px;margin-right:10px;" })

.Value(Model.selectedMfgId)

.Enable(true)

.Events(e => e.Change("ReloadGraph"))

)

<div class="chart-wrapper">

@(Html.Kendo().Chart(Model.graphData)

.Name("chart")

.Title(Model.Title)

.Legend(legend => legend

.Position(ChartLegendPosition.Bottom)

)

.SeriesDefaults(seriesDefaults =>

seriesDefaults.Column().Stack(true)

)

.Series(series =>

{

series.Column(m => m.Series1).Name(Model.Series1Label).Color("#f3ac32");

series.Column(m => m.Series2).Name(Model.Series2Label).Color("#eda6a6");

}

)

.CategoryAxis(axis => axis

.Visible(true)

.Categories(m => m.Categories)

.MajorGridLines(lines => lines.Visible(false))

.Labels(labels=>labels.Rotation(-90))

)

.ValueAxis(axis => axis

.Numeric()

.Labels(labels => labels.Format("{0}%"))

.Max(100)

.Line(line => line.Visible(false))

.MajorGridLines(lines => lines.Visible(true))

)

.Tooltip(tooltip => tooltip

.Visible(true)

.Template("#= dataItem.Tooltip #")

)

.HtmlAttributes(new { @style = "Width:400px%;" })

)

</div>

<script type="text/javascript">

function ReloadGraph() {

var mfgId = $('#mfgList').val();

var schoolYear = $('#schoolYearList').val();

$.ajax({

type: "POST",

async: true,

data: "{'mfgId':'" + mfgId + "','schoolYear':'" + schoolYear + "'}",

url: '@Url.Action("LoadGraphData", "Commodity")',

contentType: "application/json; charset=utf-8",

dataType: "json",

success: ReloadGraph_ajaxCallSucceed,

failure: ajaxCallFailed

});

}

function ReloadGraph_ajaxCallSucceed(response) {

$('#chart').data("kendoChart").dataSource.data(response.graphData);

}

function ajaxCallFailed(response) {

alert("Ajax call Failed ");

}

Error! The requested URL returned 500 - Internal Server Error

Hi all

When I load the page with the following grid, the browser show me this message "Error! The requested URL returned 500 - Internal Server Error"
Could anybody help me please?

That's my code:

(IndexRechte.cshtml)

@(Html.Telerik().Grid<GruppeFunktion>()

.Name("Grid")

.DataKeys(keys =>

{

keys.Add(o => o.GruppeFunktionID);

})

.ToolBar(commands => { commands.SubmitChanges(); })

.DataBinding(dataBinding =>

dataBinding.Ajax()

.Select("_IndexRechte", "Rechte")

.Update("_SaveBatchEditing", "Rechte")

)

.Columns(columns =>

{

columns.Bound(o => o.GruppeFunktionID);

columns.Bound(o => o.visible)

.ClientTemplate("<#=visible? 'ja' : 'nein' #>")

.Title("K")

.Width(12);

})

.ClientEvents(events => events

.OnDataBinding("Grid_onDataBinding")

.OnError("Grid_onError"))

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

.Scrollable(scrolling => scrolling.Enabled(false).Height("auto")) // ohne Scrolling zerfällt die Tabelle, wenn sie zu breit ist

.TableHtmlAttributes(new { style = "table-layout = fixed" })

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

.Sortable()

.Filterable()

.Groupable()

.Pageable(paging =>

paging

.PageSize(ViewBag.PageSize)

.Style(ViewBag.PageStyle)

.Position(GridPagerPosition.Bottom)

)

And that's the Controller:

[GridAction]

public ActionResult _IndexRechte()

{

List<GruppeFunktion> gruppeFunktion;

gruppeFunktion = (List<GruppeFunktion>)Session["gruppeFunktion"];

// vorbereitete Geschäftsliste anzeigen

return View(new GridModel<GruppeFunktion> { Data = gruppeFunktion });

}

public ViewResult IndexRechte(Guid gruppeID)

{

// PageSize

ViewBag.PageSize = PageSizeFunktionliste;

List<GruppeFunktion> gruppeFunktion = (from ObjGF in this.db.GruppeFunktion

where ObjGF.GruppeID == gruppeID

select ObjGF).ToList();

Session["gruppeFunktion"] = gruppeFunktion;

if (gruppeFunktion.ToList().Count > PageSizeFunktionliste)

{

ViewBag.PageStyle = GridPagerStyles.NextPreviousAndNumeric;

}

else

{

ViewBag.PageStyle = GridPagerStyles.Status;

}

return View();

}

Thank's a lot!

Custom Popup Editor Showing WYSIWYG editor for simple string field

I created a custom popup editor for my grid. I have two string fields, both defined with [StringLength(20)] in the model. In the custom popup editor template I use EditorFor to display an editor for both fields. One gets a standard text input as expected. One gets the WYSIWYG editor. (Screenshot attached) Color me confused. Any ideas?

The two fields I'm referring to in the template below are PowerNumber and CaseNumber.

The model definitions are:
[Required]
        [StringLength(20)]
        [Display(Name="Power")]
public string PowerNumber { get; set; }

[StringLength(20)]
        [Display(Name="Case #")]
        public string CaseNumber {get; set;}

The editor template:

@model KendoMVC4.Models.Power
@Html.HiddenFor(model => model.ID)
<div class="editor-label">
    @Html.LabelFor(model => model.PowerNumber)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.PowerNumber)
    @Html.ValidationMessageFor(model => model.PowerNumber)
</div>
<br />
<div class="editor-label">
    @Html.LabelFor(model => model.Posted)
</div>
<div class="editor-field">
    @Html.Kendo().DatePickerFor(model => model.Posted)
    @Html.ValidationMessageFor(model => model.Posted)
</div>
<br />
<div class="editor-label">
    @Html.LabelFor(model => model.Forfeited)
</div>
<div class="editor-field">
    @Html.Kendo().DatePickerFor(model => model.Forfeited)
    @Html.ValidationMessageFor(model => model.Forfeited)

</div>
<br />
<div class="editor-label">
    @Html.LabelFor(model => model.State)
</div>
<div class="editor-field">
    @(Html.Kendo().DropDownListFor(model => model.State)
            .Name("State")
            .OptionLabel("Select State")
            .DataTextField("Text")
            .DataValueField("Value")
            .Items(items =>
                {
                    items.Add().Text("Alaska").Value("AK");
                    items.Add().Text("Hawaii").Value("HI");
                    items.Add().Text("New York").Value("NY");
                    items.Add().Text("Texas").Value("TX");
                })
                )
</div>
<br />

Custom command with data save

I followed the instructions here and successfully created a custom command column which displays some text in a popup window. The next step in what I'd like to do is to have the user able to edit something on the window shown by that custom command and update the datasource. How can this be accomplished?

In other words, how can I add, for example, a DatePickerFor a particular field in the model and have a button click send that data back for update? The model being used is a list of items so it would have to be a DatePicker for the current item in the list.

Legend does not display for Column chart

Hi,

I have a column chart which does not show the legend even though I have set legend.Visible to true. If I uncomment the .Group line commented in the code below, then the legend starts showing, but unfortunately it displays the default colors rather than those I have customised with m => m.UiColor

                        

@(Html.Kendo().Chart<WorkItemStatusSummary>()
                      .Name("Chart")
                      .Legend(legend => legend
                          .Visible(true)
                          .Position(ChartLegendPosition.Bottom))
                      .DataSource(ds => ds
                        .Read(read => read
                            .Action("DummyAction", "DummyController")
                            .Data("ChartAdditionalFilterData"))
                        //.Group(g => g.Add(m => m.Status))
                      )
                      .Series(series => series.Column(m => m.Count, m => m.UiColor).Name(""))
                      .CategoryAxis(axis => axis
                                                .Categories(m => m.Status)
                      )
   )

Kendo bundling broken by new System.Web.Optimization 1.1.0

I recently updated several nuget packages in my MVC4 solution. After the update none of the kendo styles or js files were being found. I narrowed it down to the bundling, and identified it was an update to "Microsoft ASP.NET Web Optimization Framework" 1.1.0

The release notes (http://aspnetoptimization.codeplex.com/releases/view/101096) has a section at the bottom that explains why.

I thought of 3 potential solutions:

Change the IgnoreList to be applied to the new directory filters instead (I didn't try this one)
Include the kendo css and js files without using wildcards (tried this one and it works)
Include the non-minified versions of the files, taken from the 'src' folder, in my solution (tried this one and it works)

I've ended up using option 3 as it seems to work best with the intention of how the MV4C bundling should work (non-minified used in debug so can debug into kendo code, and then minified version used in release).

I'm mainly posting to help anyone else who hits this problem, but if anyone has any suggestion why option 3 is not a good option I'd like to hear.

Also Kendo should probably update the documentation as the current IgnoreList approach no longer works.

[Solved] Cascading DropDownList WITHOUT ServerFiltering

I have a DropDownList that, depending on another value, has anywhere from 5 to 15 values in it and there are about 20-25 total possible values.
It seems a bit ridiculous to go back to the server to get the proper data.
What I would like to do is render ALL of the items to the browser (as an array or something?) and do the filtering on the browser in javascript.
Has anyone done anything like this? I can't find any examples of cascading DropDownLists that don't have ServerFiltering turned on.

[Solved] Kendo Menu wierdness

Hi,

I'm trying to create a menu in my MVC 4 _Layout.cshtml file.

I started from the example and I hacked it up to show the structure I want. The problem is that when I use the syntax:
children.Add().Text("Application Home").Action("Index", "Home");

Sometimes the menu item is placed correctly with the action wired up. Other times the action appears to be causing some kind of error, (page compiles fine), but the item is not shown. If I remove the Action method, the
item shows up where it's supposed to.

I've attached the entire menu code. Can someone please help?

IE10 Paging

I have a grid setup with Ajax loading/editing, etc. Paging works fine in Chrome and Firefox but in IE10 (10.0.9200.16618) I have to turn on compatibility mode to get it to work. Without compatibility mode, paging options still show up but grid is showing all records instead of limiting to number of records set with .PageSize setting on grid. After turning on compatibility mode, the paging works but I get errors such as the attached when changing pages or opening the popup editor.

Steps to reproduce:

Paging

Change page and get the first error (attachment named PagingError.png)

Editing

Click the edit button in the grid.
First get the same error as above
Click No to debug prompt
Get second error (attachment named CouldNotContinue.png)
Click No to debug prompt
Click edit button again
Popup editor comes up but no datepicker for the date fields and date field shows "Wed Feb 13 00:00:00 CST 2013"

Any suggestions/ideas on why this is and how to correct it?

Hidden columns become visible after adding a row to the grid

I have a grid that I toggle the visibility of certain columns on and off in certain user situations.

Hiding the columns works fine, but when I add a row to the grid, the columns I hid become visible again as soon as I click the grid's "Add" button.

I'm not sure if this is desired or not, but I'd appreciate a workaround if it's not considered a bug. Thanks!

Script that hides the columns:

function SetItemGridView(isManual) {

var itemGrid = $("#ItemGrid").data("kendoGrid");

if (isManual) {

itemGrid.showColumn("MyTestCol");

} else {

itemGrid.hideColumn("MyTestCol");

}

Grid Databound function that calls SetItemGridView:

function ConfigureItemGrid(e) {

SetItemGridView($("#IsManual").length > 0 ? $("#IsManual").is(":checked") : true);

}

Grid code (simplified for brevity):
