Question around grouping. I've noticed that when the grid's read happens it calls the assigned web method as you would expect. What I have noticed that the code below produced two different results. One for grouped data and another type for all other grid alterations (filters and sorts).
Sample code:
Dim temp As IQueryable = grid.ToDataSourceResult(request).Data.AsQueryable
No grid alterations or filtering or sorting the data type of the above object is:
System.Linq.EnumerableQuery(Of myDataType)
Apply one or more groups and the data type becomes:
System.Linq.EnumerableQuery(Of Kendo.Mvc.Infrastructure.AggregateFunctionsGroup)
Why does this happen? Have we implemented something incorrectly?

Any time I try to do an update with InCell editing I get a javascript error as soon as I click out of the cell button.
function anonymous(d) {
return d.x.Col2 // 0x800a138f - JavaScript runtime error: Unable to get property 'Col2' of undefined or null reference
}
The d value seems to have my object (CP_FailureStrategyMatrixRow) in it just fine, i.e. it has a attribute called "Col2" that has a valid value in it. I feel everything would work just fine if it was doing "d.Col2", instead of looking in some inner value called x. But I have no idea where this "x" is coming from.
It never even gets to the server-side code:
I have tried it with both versions of the CRUD operations, as the examples on telerik seem to use both, but it doesn't seem to matter which update statement I use.

Every time the chart is drawn the background is set to gray. No matter if the theme is specified or not or if the chart area background is set to "", "transparent" or any color, or not at all.
You can see a blank chart with the correct background color prior to the read occurring and the chart being redrawn with the appropriate data. Each path element in the SVG has a stroke color set to "#dfdfdf"
Here is the code:
@(Html.Kendo( ).Chart<ViewModels.HistoryChartModel>( )
.Name( "chart" )
.ChartArea(c=>c.Width(800).Height(600))
.DataSource( dataSource => dataSource
.Read( read => read.Action( "Series", "Home" ) )
.Group( group => group.Add( model => model.BasinName ) )
.Sort( sort => sort.Add( model => model.ReadingDateTime ).Descending( ))
)
.Series( series => {series.Line( model => model.LevelReading ).Name( "#= group.value # " ).Markers(false);} )
.Legend( legend => legend.Position( ChartLegendPosition.Bottom ))
.ValueAxis( a => a.Numeric( ).Min( 3 ).Max(10).MinorTicks(mt=>mt.Visible(false)).MajorUnit(.5) )
)

I have a Razor for that has several Autocomplete fields on it.
Some of these fields are required, some are not required.
I need to show the required fields in a red border and a blue background, while non-required fields are white, with a blue border.
My css works for a regular text field, but i cannot figure out how to make it work for an autocomplete field.
How would I do that? I have tried " .HtmlAttributes(new { @class="rsireqtext",style = "width: 99%;" }) " in the autocomplete (rsireqtext is my 'required' styling),
but that doesn't do it.
Any ideas?
TIA,

Using Kendo UI for ASP.NET MVC, I am creating and passing in a Model that contains a collection of objects (called ChartSeries) that has fields for Color, SeriesName, and a collection of a second class (ChartSeriesValue) which contains fields Value, Date. I am trying to create a line chart using this local data with a dynamic number of series. Using a foreach statement, I can get the different series values plotted, but am unable to get the Dates to display using CategoryAxis. Will I have to go the route of using DataSource to group the flattened data, or is it possible to accomplish this using localdata?
Here are the chart-related classes I am using:
public class ChartSeries { public string SeriesName { get; set; } public string ValueType { get; set; } public string HexColor { get; set; } public IList<ChartSeriesValue> ChartSeriesValues { get; set; } }public class ChartSeriesValue { public decimal? Value { get; set; } public DateTime Effective { get; set; } }
Thus far, I have been able to get either the lines with proper values, or just the X-Axis date labels to display, but not both. Here's my current attempt that displays proper line series data without X-Axis labels:
@(Html.Kendo().Chart<ChartSeriesValue>() .Name("myChart_" + Model.MyChart.Id) .Title(Model.MyChart.Name) .Legend(legend => legend .Position(ChartLegendPosition.Bottom) ) .ChartArea(chartArea => chartArea .Background("transparent") .Width(250) .Height(250) ) .SeriesDefaults(seriesDefaults => seriesDefaults.Line().Style(ChartLineStyle.Smooth) ) .Series(series => { if (!Model.ChartSeriesList.IsNullOrEmpty()) { foreach (var metSeries in Model.ChartSeriesList) { if (!metSeries.ChartSeriesValues.IsNullOrEmpty()) { series.Line(metSeries.ChartSeriesValues) .Field("Value") .Name(metSeries.SeriesName) .Color(metSeries.HexColor); } } } }) .CategoryAxis(axis => axis .Categories(x => x.Effective.Date) .Name("Effective Date") //.Name("Effective") //.MajorGridLines(lines => lines.Visible(true)) //.Date().BaseUnit(ChartAxisBaseUnit.Months) .Labels(labels => labels.Visible(true)) .Color("Red")//.Rotation(-60)) //.Type(ChartCategoryAxisType.Date) ) ))
Please let me know if you need further clarification. Thanks!
