[Solved] StepLine series

Hello,

Is there some way to plot Stepline series and Line series on the same graph ? I have a cartesian chart with several line and area series and I would like to add stepline serie without modifying my data (e.g. without adding a Y value at each X to have the constant line).

Another question, is it possible to change the base line of an area series so that color fill stops at a specific Y value ?

[Solved] Bar chart bars are very thin for some datasets!

Hi,

Sometimes the bars are extremely thin for some sparse datasets. When I display a bar chart with a DateTimeContinuousAxis horizontal axis, spanning just a few hours with only 2 or 3 items, the bars are extremely thin. If I change the timespan to a day, also with just a few items, the bars look normal (see attached screenshots). I'm using UI for WPF Q2 2016, Is this s bug?

Thanks,

Brian

I am sure this was working but I am not seeing the correct output now:

Row Data Context Property

[Display(Name = "Start Date")]

[DisplayFormat(DataFormatString = "{0:d}")]

public DateTime ClaimDate { get; set; }

XAML in the View

<telerik:RadGridView VerticalAlignment="Stretch" CanUserDeleteRows="False" CanUserFreezeColumns="False" CanUserInsertRows="False" CanUserReorderColumns="False" CanUserSearch="False" ShowGroupPanel="False"

ShowSearchPanel="False" ItemsSource="{Binding Data.ItemsSource}" BorderBrush="Transparent" IsReadOnly="True" ShowToolTipOnTrimmedText="True" RowIndicatorVisibility="Collapsed"

SelectionMode="Single" IsFilteringAllowed="False" AlternationCount="2">

</telerik:RadGridView>

C# Interactive Window

> DateTime.Today.ToString("d")

"05/09/2017"

Screenshots are attached.

Any ideas?

Thanks,

[Solved] how to re-apply StyleSelector and TemplateSelector on GridViewRow

I have some columns with `CellStyleSelector` and `CellTemplateSelector` which associating with a property in row data, when the property changed in code behide, both StyleSelector and TemplateSelector are not refreshed.

now I have got the row which need to refresh from `ItemContainerGenerator`, but have no idea to do that.

RadGridView.Rebind() works but it might be a little heavy.

public void RefreshRowTheme(object rowData)

{

var container = this.grid.ItemContainerGenerator.ContainerFromItem(rowData);

if (container != null)

{

var row = container as GridViewRow;

if (row != null)

{

//how to re-apply StyleSelector and TemplateSelector on all cells

}

Thanks.

[Solved] Saveing of Expand/Collapse groups status

Hello,

I have a gridview control which items is automatically updated from time to time. A user has ability to group items in the grid (using standard drag and drop approach). However, after items updating groups collapse, even if they were expanded. If I set AutoExpandGroups = false, groups will be always expanded after update.

I would like to save expand/collapse group status. Is it possible to implement?

Thank you in advance
