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

Data Annotations Date Format

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,
Maurice

[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

Glyphs with implicit styles

I was reading about using glyphs the other day and it sounds very interesting, but it's not clear from any of the documentation how to use them with implicit styles.

The overview page says "In order to use the glyph references and the font as StaticResources in a project, you need to include the Telerik.Windows.Controls.dll and merge the required dictionary in the application resources.", but I am using all "no xaml" files, so I'm not really sure how those things fit together.
