What does the RadDragAndDropManager framework use to determine the position of the mouse cursor in relation to the mouse cursor? It's off significantly for me. The farther right I move, the more the cue drifts away from the mouse cursor. It gets closer as I move to the left of the window, but at its closest point, it's still at least an inch away. I'm aware of the RadDragAndDropManager.DragCueOffset property, but it seems the offset varies on different computers.

ViewModel Setting bound property to null does not remove grid selection

I have a RadGrid that has its SelectedItem property bound to a property in my ViewModel. In my ViewModel, if I set the item that is bound to the selected item equal to null I would expect that the selection would be removed from the RadGrid, but it does not.
XAML:

    
            <telerik:RadGridView Grid.ColumnSpan="2" SelectedItem="{Binding Path=WorkingMedicationOrder.DrugDosage_, Mode=TwoWay}" ItemsSource="{Binding DrugDosages}" Grid.Row="5" AutoGenerateColumns="False" ShowGroupPanel="False">

In my ViewModel I do the following expecting the SelectedItem in the RadGrid to be removed.

WorkingMedicationOrder.DrugDosage_ =

null;

Thanks,

Align AxisY on multiple charts that are stacked

I have a scenario where I need to have multiple charts stacked. I want to know how I could set the distances on the labels for the Y axis so that all of the charts line up. If the charts have different label precision and formatting, they do not line up and this is not desirable. Please advise.

Thanks,
David

How to prevent RadGridView auto row resizing?

I have a telerik RadGridView in which some columns can have a lot of data causing them to go multiline, which is fine. However, when we scroll horizontally and those multiline column data is out of view, the rows resize back to single line. We would like to avoid this.

DataGridView has a AutoSizeRowsMode but I can't find an equivalent RadGridView property.



Help?

[Solved] Using the CollectionViewSource

Hello I recently tried to use a CollectionViewSource as the items source for the RadGridView in WPF. I wanted to do so for the ammount of filtering that I needed. Coming from a Windows development background that was "the way" to do it. I am new to my company and I am not trying to fall behind. Is there an example of how to do this? In C# all we have to do to apply a filter is add a filter event handler, but when I would do this the RadGrid would "hiccup." I ended up having to use a dataview object before pulling my hair out. I refuse to write for loops with the invention of generics in the .Net framework. Any and all help is appreciated.

CheckBoxColumn and Toolbar

Hi,

I have a grid with a checkbox column, which is bounded to a boolean property
and a toolbar with a Remove command.

The remove command should be enabled only if at least one element in the grid is checked.
The command logic resides in a View Model.

The problem i'm facing is that the Remove button is updated (enabled/disabled) only after
i move focus from the checkbox cell- I would like the button to update upon check/uncheck the checkbox.

Thank you,
Koby

Fixed overlays possible?

I'm hosting the WPF control in a WinForms project. I currently have a label positioned over the map for informational messages, such as 'drawing map' or 'no data selected'. However when the map is resized or panned, the label and/or the map are drawn incorrectly, or not at all. Is there a built-in overlay available in the map that is fixed to screen coordinates, rather than geographic coordinates? Similar to how the mouse position and scale never move.

EndEdit not firing from TreeViewItem editing

I have a class (lets say CAR) that implements IEditableObject. If i bind a collection of cars to a datagrid, on editing a car, EndEdit on CAR is fired. However, my cars collection is displayed in a treeview. When i edit a CAR using the controls in my treeviewitem , the EndEdit is not raised. It's driving me crazy. Any clues ?

Tile View Item Selection

Hi everybody,

I ask for a specific cuestion about RadTileView. I would like to display the tile items in "read-only" mode (IsEnable = false no valid xD). What I mean is that I present each item without the button for maximize/minimize. For that I took some piece of code I saw in one of your examples. It works properly but a problem raises when a tile item is selected because it is not highlighted. The code appears in the following snippet:

telerik:RadTileView Name="RadTileViewUsers"

ContentTemplate="{StaticResource ContentTemplate}"

ItemTemplate="{StaticResource ItemTemplate}"

MinimizedColumnWidth="150" MinimizedRowHeight="150"

RowHeight="120"

ColumnWidth="147"

MaximizeMode="Zero"

PreviewTileDragStarted="RadTileViewUsers_PreviewTileDragStarted"

ItemContainerStyle="{StaticResource RadTileViewItemStyle}"

PreservePositionWhenMaximized="True" IsVirtualizing="True" IsSelectionEnabled="True" />

And the style (ignoring the colors):

<Style x:Key="RadTileViewItemStyle" TargetType="telerik:RadTileViewItem">

<Setter Property="telerik:RadDragAndDropManager.AllowDrag" Value="True" />

<Setter Property="HorizontalContentAlignment" Value="Stretch" />

<Setter Property="VerticalContentAlignment" Value="Stretch" />

<Setter Property="Background" Value="{StaticResource TileView_Background}" />

<Setter Property="BorderBrush" Value="{StaticResource TileView_OuterBorder}" />

<Setter Property="BorderThickness" Value="1" />

<Setter Property="Padding" Value="7" />

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="telerik:RadTileViewItem">

<Grid>

<Border x:Name="outerBorder"

Margin="{TemplateBinding Padding}"

Background="{TemplateBinding Background}"

BorderBrush="{TemplateBinding BorderBrush}"

BorderThickness="{TemplateBinding BorderThickness}"

CornerRadius="{StaticResource TileView_OuterBorder_CornerRadius}">

<Border x:Name="outerContainer"

Background="Transparent"

BorderBrush="{StaticResource TileView_InneBorder}"

BorderThickness="{StaticResource TileView_InneBorder_Thickness}"

CornerRadius="{StaticResource TileView_InneBorder_CornerRadius}">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<StackPanel>

<Border Background="{StaticResource TileView_HeaderBackground}"

BorderBrush="{StaticResource TileView_HeaderBorder}"

BorderThickness="{StaticResource TileView_HeaderBorder_Thickness}"

CornerRadius="{StaticResource TileView_HeaderBorder_CornerRadius}"

Padding="10 0 7 0">

<Grid MinHeight="28">

<Border x:Name="GripBarElement" Background="Transparent">

<ContentPresenter x:Name="HeaderElement"

Margin="0,0,10,0"

HorizontalAlignment="Left"

VerticalAlignment="Center"

ContentTemplate="{TemplateBinding HeaderTemplate}" />

</Border>

<!--

<telerik:RadToggleButton x:Name="MaximizeToggleButton"

Command="tileView:TileViewCommands.ToggleTileState"

Style="{StaticResource maximizeToggleStyle}" />

-->

<!--<StackPanel HorizontalAlignment="Right" Orientation="Horizontal">

<telerik:RadButton >Refresh</telerik:RadButton>

<telerik:RadButton >Minimize</telerik:RadButton>

<telerik:RadButton >Maximize</telerik:RadButton>

</StackPanel>-->

</Grid>

</Border>

<Border x:Name="Splitter"

Height="4"

Background="{StaticResource TileView_HeaderBorder_HorizontalSplitterBackground}"

BorderThickness="0"

OpacityMask="{StaticResource TileView_HeaderBorder_HorizontalSplitterOpacityMask}" />

</StackPanel>

<Grid Grid.Row="1" Background="Transparent">

<ContentPresenter x:Name="ContentElement"

Grid.Row="1"

HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"

VerticalAlignment="{TemplateBinding VerticalContentAlignment}"

Content="{TemplateBinding Content}"

ContentTemplate="{TemplateBinding ContentTemplate}" />

</Grid>

<Rectangle x:Name="DisabledVisual"

Grid.RowSpan="2"

Fill="{StaticResource DisabledBrush}"

RadiusX="4"

RadiusY="4"

Visibility="Collapsed" />

</Grid>

</Border>

<Grid x:Name="SelectedItem"

Margin="-1"

Visibility="Collapsed">

<Border Margin="{TemplateBinding Padding}"

BorderBrush="{StaticResource ControlOuterBorder_Selected}"

BorderThickness="2"

CornerRadius="{StaticResource TileView_OuterBorder_CornerRadius}" />

</Grid>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

Note: If I change Visibility value to Visible in Grid "SelectedItem" all the item appear as selected.

Do you have any suggestion for solving my problem?

Thanks in advance.

Eduardo.
