Currently i am using RadGridView control in one of my project. I need some clarification for below items,

• How to filter column values based on background color as well as actual value?
• If not possible means, then how to create custom filter for color filter with existing filter option.

I have already spent lot of time on it. But i didnt find an exact solution. Could you please help me on this?

Note :

I have tried below options,

• Used "FilterMemberPath" to map another property .
• Created custom control for color filter. But not able to use exisitng functionality.

Thanks in advance.

How I can do server-side paging/sorting/filtering in a RadDataGrid. I retrieve the data from an azure function and I don't want to retrieve all data from the database. I pass as a parameter to the azure function, the page index, and the page size.  the response returns the result of the LINQ query with Skip(page index) and Take(page Size), and total row count.

Thank you for your help.

Hey, I'm building an app using Telerik for WPF, I want to minimize a tab when a variable change(using data binding) and I cannot find any answers across the web.

When I set the isHidden property to true, I can't set it back to false(because when isHidden set to true, the pane is removed from the visual tree), so I tried many other things to conditional minimizing the pane but didn't figure it out.

Sincerely, Omer

Hello.

In radgridview i change the colors of the cells in the cellloaded event, which wotks fine, but

is there any way to use doubleanimate the backgroudn color of a cell?

This is how i color now:

Private Sub dgw_PL_CellLoaded(sender As Object, e As CellEventArgs) Handles dgw_PL.CellLoaded
        If TypeOf e.Cell Is GridViewHeaderCell Or TypeOf e.Cell Is GridViewFooterCell Then
            Exit Sub
        End If
        If e.Cell.Column.DisplayIndex < 7 Then
            e.Cell.Background = Brushes.LightSteelBlue
        End If
        Dim G As Telerik.Windows.Controls.GridView.GridViewCell = e.Cell
        If e.Cell.Column.UniqueName.ToString.ToUpper.Contains("DEM") Then
            If e.Cell.Column.DisplayIndex > 6 AndAlso (G.Content.text = "0" Or G.Value > 0) Then
                G.Background = New SolidColorBrush(Color.FromRgb(200, 255, 215))
            End If
        End If
End Sub

How could i make it for example blink between two colors, with doubleanimation?

Thanks

Peter

Hi,

I'm using SeriesDescriptorSelector + SeriesDesciptor i order to create series.

Based on the viewmodel info. the axis series are also created on when the series are  created, on CreateInstanceCore method.

Evething works fin except the axis TitleTemplate.

protected override ChartSeries CreateInstanceCore(object context)
        {
            IChartSerieViewModel viewModel = context as IChartSerieViewModel;
            var result = base.CreateInstanceCore(context);
            viewModel.ChartSeries = result;

            var scl = (viewModel.ChartSeries as ScatterLineSeries);

            scl.HorizontalAxis = new LinearAxis();
            scl.HorizontalAxis.DataContext = viewModel.SerieSettings.HorizontalAxis;
            viewModel.SerieSettings.HorizontalAxis.Bind(scl.HorizontalAxis);

            scl.VerticalAxis = new LinearAxis();
            scl.VerticalAxis.DataContext = viewModel.SerieSettings.VerticalAxis;

            return result;
        }

here is the Bind method

 public void Bind(CartesianAxis axis)
        {
            if (axis == null)
                return;

            SetLabelIntervalAxisBinding(axis, nameof(LabelInterval), this);
            SetLabelFormatAxisBinding(axis, nameof(LabelFormat), this);
            SetTitleAxisBinding(axis, nameof(Title), this);
            SetVisbilityBinding(axis, nameof(IsVisible), this);
            if (axis is LinearAxis)
            {
                SetMaxAxisBinding(axis as LinearAxis, nameof(Maximum), this);
                SetMinAxisBinding(axis as LinearAxis, nameof(Minimum), this);
            }
            if (axis is CategoricalAxis)
            {
                (axis as CategoricalAxis).PlotMode = Telerik.Charting.AxisPlotMode.OnTicksPadded;
                (axis as CategoricalAxis).MajorTickInterval = 1;
            }
            SetColorAxisBinding(axis, nameof(AxisColor), this);

            var rers = axis.FindResource("AxisTemplateTitle");

            axis.TitleTemplate = Application.Current.Resources["AxisTemplateTitle"] as DataTemplate;
        }

like I said, the binding works fine,, but even if the TitleTemplate is set, the chart won't display the title.

Any info is highly appreciated.

Thank you

I have used the provided CategoryViewModel to implement RadTreeView tristate logic with checkboxes and also Enable/disable of some items by using isChecked and isEnabled properties.

Now  i need to implement Expand and Collapse when i check a parent item (subcategory item )

Could you pls suggest which events and how to use.

Hi,

I'm trying to use the ScheduleView control to create a kind of calender for shift planning. (a bit like the Shifts app in Teams)
But I'm having some troubles styling it in the way I want.

Based on the documentation, I have this at the moment.

<telerik:RadScheduleView x:Name="ScheduleView" AppointmentsSource="{Binding Appointments}">
	<telerik:RadScheduleView.ViewDefinitions>
		<!--<telerik:DayViewDefinition/>-->
		<telerik:WeekViewDefinition Orientation="Vertical" ShowWeekGroupHeaders="True" ShowAllDayArea="False" ShowTimeRuler="True" MinorTickLength="1d" MajorTickLength="1d" WeekGroupHeaderStringFormat="Week number {0}, {1:D}" FirstDayOfWeek="Monday"/>
	</telerik:RadScheduleView.ViewDefinitions>
	<telerik:RadScheduleView.ResourceTypesSource>
		<telerik:ResourceTypeCollection>
			<telerik:ResourceType Name="Team">
				<telerik:Resource ResourceName="DAG" DisplayName="Dag"/>
				<telerik:Resource ResourceName="PL1" DisplayName="Ploeg 1"/>
				<telerik:Resource ResourceName="PL2" DisplayName="Ploeg 2"/>
				<telerik:Resource ResourceName="NA" DisplayName="Nacht"/>
				<telerik:Resource ResourceName="WK1" DisplayName="Weekend 1"/>
				<telerik:Resource ResourceName="WK2" DisplayName="Weekend 2"/>
			</telerik:ResourceType>
		</telerik:ResourceTypeCollection>
	</telerik:RadScheduleView.ResourceTypesSource>
	<telerik:RadScheduleView.GroupDescriptionsSource>
		<telerik:GroupDescriptionCollection>
			<telerik:DateGroupDescription/>
			<telerik:ResourceGroupDescription ResourceType="Team"/>
		</telerik:GroupDescriptionCollection>
	</telerik:RadScheduleView.GroupDescriptionsSource>
</telerik:RadScheduleView>

This is already pretty close to what I need. But I want my Team resource to be displayed horizontally.
The goal is that per day, I can fill in if for that team it's a working day or a not. So 1 entry per day per team. (I don't care about the shift timing yet since it's fixed per shift anyway)

Something like this

Is this possible? And could somebody help me guide me in the right direction please? :-)

Hello, 

We are needing to retrieve all map tiles for both Bing and Open Street over https instead of http. Using this forum post we were able to successfully retrieve Open Street tiles over https.

https://www.telerik.com/forums/openstreetmapprovider-through-https#1146262

However after structuring the Bing requests similarly, it appears the initialization of the Bing map service will only go out over http. With only https allowed through the firewall, this call fails and the tiles are never retrieved. If we open http, then the initialization is successful, and the map tiles will come through over https. 

This is an example of the Bing endpoint that is only requested over http while launching the map. 

Is there a way to override the initialization or imagery setup with Bing, to have all the mapping calls use https, similar to the GetTile override? 

Example Code In Use:

namespace Map.RadMap
{
    public class CustomHttpsMapProvider : TiledProvider
    {
        public CustomHttpsMapProvider(MapMode mapMode = MapMode.Road, bool hasLabels = false, string applicationId = Strings.BING_MAPS_KEY, string osmUserAgent = null)
              : base()
        {
            // Open Street
            if (osmUserAgent != null)
            {
                OsmTileMapSource source = new HttpsOpenStreetMapSource();
                source.WebHeaders.Add(HttpRequestHeader.UserAgent, osmUserAgent);
                this.MapSources.Add(source.UniqueId, source);
                return;
            }

            // Bing Hybrid, Aerial or Road
            switch (mapMode)
            {
                case MapMode.Aerial:
                    {
                        if (hasLabels)
                        {
                            BingRestAerialLabelSource source = new HttpsBingAerialLabelSource(applicationId);
                            MapSources.Add(source.UniqueId, source);
                        }
                        else
                        {
                            BingRestAerialSource source = new HttpsBingAerialSource(applicationId);
                            MapSources.Add(source.UniqueId, source);
                        }
                        break;
                    }

                case MapMode.Road:
                    {
                        BingRestRoadSource source = new HttpsBingRoadSource(applicationId);
                        MapSources.Add(source.UniqueId, source);
                        break;
                    }

In a RadCartesianChart, zero values and very small values (relative to the Maximum of the axis) don't show up.  I would like to have them show up as a horizontal line, like in the attached picture.

I got that picture by setting a small value for y.  But if you increase the height the chart, it starts to look like the bar has some height rather than just being a horizontal line.

Is there a better way to get zeros to show up?
