Hello,

Regarding this forum question, it will be good if you add the attached property VisibleColumnsCount or IsAnyColumnVisible so I can hide the rows when there are 0 columns. Please read the following link for full information:

Hello

Good job with the Fluent theme! I'm using the core styles with validation in my GridViews and have noticed that the bottom border is not/barely visible in invalid grid cells (see attached screenshot).

I can fix this by taking a copy of GridViewCellCoreValidationTemplate and adding Margin="0 0 0 1" to Background_Invalid.

Cheers

The issue is reproduced only when the items in the source collection have properties with duplicated values and they are sorted before the selection is processed. If the property values are unique or the SelectionMode is set to Multiple, the selection works as expected both with sorted and unsorted data. The workaround is to use either Multiple SelectionMode, or Cell/Mixed SelectionUnit.

Currently, the GridViewMergedCell cannot be selected. Allow selecting the merged cells via the UI or code. 

At the moment RadGridView has only a CurrentMergedCell property.

In the following scenario:

<telerik:RadGridView x:Name="clubsGrid" ItemsSource="{Binding Foos}" AutoGenerateColumns="False">
	<telerik:RadGridView.Columns>
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo1}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo2}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo3}" Width="*" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo4}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo5}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo6}" MinWidth="100" />
	</telerik:RadGridView.Columns>
</telerik:RadGridView>

<DataGrid ItemsSource="{Binding Foos}" AutoGenerateColumns="False" Grid.Row="1">
	<DataGrid.Columns>
		<DataGridTextColumn Binding="{Binding Foo1}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo2}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo3}" Width="*" />
		<DataGridTextColumn Binding="{Binding Foo4}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo5}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo6}" MinWidth="100" />
	</DataGrid.Columns>
</DataGrid>

in the native DataGrid after the Width of Foo4 column is increased towards Foo3, then the Width of Foo5/Foo6 columns can also be increased. We can implement similar behavior in the RadGridView as well. 

Pixel bug in Lightweight Templates of RadGridView in VisualStudio2013 and Office2013 themes:

No horizontal grid lines when cell has background color:

Most likely bottom margin of PART_CellBorder not set in VisualStudio2013 Theme. In Office2016 PART_CellBorder.Margin="0 0 0 1"

• Open the GridView examples
• In the available examples, select "Selection and Usability | Row Details"
• Select a row in the grid view
• In the external Details Presenter, select : nothing is displayed in the bottom.
• You have to select another row and then come back to show the detail.

The fix for this issue will be available with the next LIB (version 2018.3.1217) expected on Monday, December 17.

MergedCellsStyle and MergedCellsStyleSelector properties will be available with Q2 2016.
