Styling RadGridView Cells.

I have a GridView with several columns. I am using a subset of columns to the right to show bars like a kind of Gantt chart.

I want to style the cells in the rows in such a way that each Cell merge with the cell to its left and the cell to its right (no merge with above or below cells) in order to produce the impression that there is a horizontal bar created by setting the background color.

I set up padding and also margin to (0,10, 0,10) in the Cell Template and hidden the columns vertical lines but I still get a gap between the cells.
I also created a GridViewCellStyle copied from the default as suggested in the documentation, I assigned to the DataColumns tag but make no difference. I can't get rid of the gaps. So I may be doing something wrong.

1. Could you be so kind of tell me how can I get this result.

2. I need to change the name of the columns header dynamically. I can do it from code behind but if I want to do it from XAML how I do that?

Thanks

Hello,

I want to use a RadWindow as a user control inside another RadWindow, like as below.

<

telerik:RadWindow x:Class="MacFellow.WPF.ParentRadWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

</

Checkbox Status Incorrect in Floating Panel(?)

Hi,
We have a RadTreeView nested in a RadPanelBar which the user can undock and have floating. While docked the binding for the all data works fine including the state of the checkboxes. However, when the undocked and floating the checkboxes no longer reflect the correct state. The names for the hierarchical data items are displaying correctly so some of the binding is still working but not the state of the checkboxes.

The following is the xaml we are using:

<telerikNavigation:RadPanelBarItem Collapsed="RadPanelBarItem_ExpandedCollapsed" Expanded="RadPanelBarItem_ExpandedCollapsed" >

<telerikNavigation:RadPanelBarItem.Header>

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="18" />

<ColumnDefinition />

</Grid.ColumnDefinitions>

<CheckBox Grid.Column="0" IsThreeState="True" IsChecked="{Binding IsDomainsChecked, Mode=TwoWay, NotifyOnTargetUpdated=True}" Click="FilterCheckBox_Click" TargetUpdated="CheckBox_TargetUpdated"/>

<TextBlock Grid.Column="1" Text="Domains"/>

</Grid>

</telerikNavigation:RadPanelBarItem.Header>

<telerikNavigation:RadTreeView

Name="DomainTreeView"

IsOptionElementsEnabled="True"

ItemsOptionListType="CheckList"

IsTriStateMode="True" Checked="TreeView_CheckedUnchecked" Unchecked="TreeView_CheckedUnchecked"

ItemsSource="{Binding Path=DomainEmailTypes}">

<telerikNavigation:RadTreeView.ItemTemplate>

<HierarchicalDataTemplate DataType="{x:Type ViewModels:EmailTypeFilterViewModel}" ItemsSource="{Binding Path=EmailTypes}">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<TextBlock Grid.Column="0" Text="{Binding Path=Name}"/>

<TextBlock Grid.Column="1" Margin="5,0,5,0" Text="{Binding Path=DisplayCount}" />

</Grid>

<HierarchicalDataTemplate.ItemTemplate>

<DataTemplate>

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<TextBlock Grid.Column="0" Text="{Binding Path=Name}"/>

<TextBlock Grid.Column="1" Margin="5,0,5,0" Text="{Binding Path=DisplayCount}" />

</Grid>

</DataTemplate>

</HierarchicalDataTemplate.ItemTemplate>

</HierarchicalDataTemplate>

</telerikNavigation:RadTreeView.ItemTemplate>

</telerikNavigation:RadTreeView>

</telerikNavigation:RadPanelBarItem>

Any help or insight would be greatly appreciated.

Thank you.

Filtering problem

I have gridview with check boxes that needs a filtering function. The problem with the default filter is that if a user opens the filter dialog an selects an item from the list all of the checked/selected items in the gridview are removed. I thought that I could add the checked items to the filter descriptor just prior to the filter event but it removes everything else from the filter list as well. Does anyone know a way around this problem?
I think what I need is the actual filterdescriptor that is being applied at the time the UI is active. I need to add my filterdescriptor to it or add a columndescriptor.
