MVVM ColumnDefinitions

Hello, is there a possibility to bind a list of columndefinition in viewmodel on GanttGrid without direct access to the gantcontrol (gantt.Columns.add)?
Best Regards Robert ...

public void InitGanttColumns()

{

//Title ----

ColumnDefinition GanttColumn = new TreeColumnDefinition();

GanttColumn.Header = "Title";

GanttColumn.Width = 200;

GanttColumn.MemberBinding = new Binding("Title");

GanttColumns.Add(GanttColumn);

// Start ----

GanttColumn = new ColumnDefinition();

GanttColumn.Header = "Start";

GanttColumn.Width = 100;

var itemsBinding = new Binding("Start")

{

Converter = new GanttModuleTypeConverter(),

ConverterParameter = "date"

};

GanttColumn.MemberBinding = itemsBinding;

GanttColumns.Add(GanttColumn);

// End ----

GanttColumn = new ColumnDefinition();

GanttColumn.Header = "End";

GanttColumn.Width = 100;

itemsBinding = new Binding("End")

{

Converter = new GanttModuleTypeConverter(),

ConverterParameter = "date"

};

GanttColumn.MemberBinding = itemsBinding;

GanttColumns.Add(GanttColumn);

}

RadTreeView going crazy

I'm not sure how to make this happen, but the treeview starts going up and down like crazy.

http://www.screencast.com/users/mpospese/folders/Jing/media/92455cfb-e015-4280-b150-c1479f6be421

(Scroll to the right, the treeview is docked on the right side of the window)

Have you ever seen this before? How can we solve it?

Thanks!

DataContext of GridViewColumns not inherited

Hello!
With the Q2 2014 version, there seems to be some breaking change in the Column handling of the RadGridView:

With the Q1 version, the DataContext of the columns was inherited, however, with the newer Q2 versions (also with the recent one), this is not the case for _one_ of our GridViews. All (or at least most) others are still working fine, but I do not see the difference to the grid where it fails.

Do you have any idea what could be the reason that the datacontext of the columns is not inherited - or how I could debug it? The columns are - obviously - not in the visual tree - so with Snoop I only see that the datacontext is not set, but I don't see the reason why...

Scrolling

I am using a radpivotgrid which is inside a radpane which is inside a radsplitcontainer. I tehn have the field list in a separate container to the right so I can resize, move and float the field list.

One of these controls (I suspect the split container) automatically shows vertical and horizontal scroll bars when necessary and what I want to do is grab these scoll positions when the users scrolls, save them and then next time restore them so the content is scrolled as they last saw it.

I cannot seem to find any events or properties that would do this for me in any of these controls. Can you tell me whether this is possible and if so how I go about it

Thanks

Apply style to main window

Hi,

using your winforms controls I can change the style of the main window of my application relatively easily

How do I change the style of my main window to the Office_Black theme using WPF controls...

I can see how to set the default theme however this only seems to affect the controls within the window not the border of the window itself.

I have tried using the RadWindow but this only creates a sub window with the defined style, and does not set the main window style

many thansk

Dragging shapes

Hi Guys,

A while back we were in contact with you regarding dragging shapes without they change position. TicketID: 662635.

We implemented the solution you guys suggested.

Now we have discovered a bug regarding the way we drag shapes.

The problem is because we set Handled = true in DragPreview, when dragged shape is dropped outside the diagram, the drag operation is never ended.

Issue here is we implemented a DragAdorner that follows the cursor, and when it re-enters the diagram the drag operation is still active. Even though the mouse button is not pressed. The issues also exists in the sample projects from the support ticket. (No dragTemple, but changed cursor)

Is there a way we can end the drag operation, when MouseLeftButtonUp occurs outside diagram.

/Anders

How to handle custom row delete

I have a DataGrid that is bound to a the Values in a ObservableDictionary (my own class) instead of the traditional ObservableCollection. Because of this, I cannot use the build in delete mechanism of the GridView. I therefore need to implement my own custom delete behavior on the current selected row when the Delete button is pressed.

My problem is that I cannot get an event when the delete button is pressed. Neither the Deleted, Deleting or KeyDown events for the DataGrid is firing. The CanUserDeleteRows property is set to true.

How can I get an event to fire when the Delete key is pressed?

Virtualization loads all items for each group

I bound a RadGridView to a VirtualQueryableCollectionView backed by SQL using System.Data.Linq.ITable.

At first Virtualization works nicely as I see that the LoadSize is submitted to the SQL provider (tracing SQL queries).
Once I add grouping (dragging a column into the grouping panel) all rows for each group are loaded.

<telerik:RadGridView x:Name="Table" ItemsSource="{Binding Data}" AutoGenerateColumns="False" IsReadOnly="True"
Height="500" Width="500"
GroupRenderMode="Flat"
CanUserInsertRows="False" CanUserDeleteRows="False"
EnableRowVirtualization="True" EnableColumnVirtualization="True"
ScrollMode="Deferred"/>

Is UI virtualization supported in a group scenario? Am I missing some settings?

[Solved] Border over RadRibbonWindow

Hello

I need to draw a border over the RadRibbonWindow, excluding the TitleBar.

I've attached an image where on the left you can see what I'm actually doing and on the right what I want to achieve.

How can I achieve that?

Code:

<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>

<telerik:RadRibbonView ApplicationName="DocumentSelector">
<telerik:RadRibbonTab Header="Documents" />
</telerik:RadRibbonView>

<Border Grid.Row="0"
Grid.RowSpan="2">
<Border.Background>
<SolidColorBrush Opacity="0.5" Color="Red" />
</Border.Background>
</Border>
</Grid>
