GridView with Group causes odd behaviors when editing

Hi Again,
I am using the grouping feature of the GridView and have just discovered some odd behavior when editing. I am using version 2013.2.611.40.
Refer to the attached image for an illustration of the behavior. My GridView has two columns, the first of which is read only. When I tab to the second column and hit F2 it enters edit mode as expected. When I tab out of the cell, the next row is repositioned as the top row in the group and the previous first row is now at the bottom of the group. This behavior persists with each tab. In addition if I escape (twice) out of the edit all keyboard navigation ceases to work; tab (shift tab) and all arrow keys. If I use the mouse to move to another cell, the navigation begins to work again; however the repositioning of the rows continues. I have been unable to reproduce this behavior in the Telerik Demos, so I am at a total loss as to what could be causing this. Obviously, I must find a solution to this. Below is the xaml for the GridView.

<telerik:RadGridView x:Name="AccountGroupsGridView"

HorizontalAlignment="Stretch"

VerticalAlignment="Stretch"

Width="{Binding ElementName=LayoutRoot, Path=ActualWidth}"

Height="{Binding ElementName=LayoutRoot, Path=ActualHeight}"

ScrollViewer.VerticalScrollBarVisibility="Auto"

ScrollViewer.HorizontalScrollBarVisibility="Auto"

IsSynchronizedWithCurrentItem="True"

AutoGenerateColumns="False"

VerticalGridLinesBrush="Transparent"

AlternationCount="2"

AlternateRowBackground="AliceBlue"

CanUserDeleteRows="True"

CanUserInsertRows="True"

ColumnWidth="*"

ShowGroupPanel="False"

RowIndicatorVisibility="Collapsed"

Focusable="False"

ItemsSource="{Binding Path=AccountGroups}">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn x:Name="AccountGroupCodeColumn"

UniqueName="AccountGroupCodeColumn"

Header="{x:Static localProperties:Resources.Account_Group_Code}"

DataMemberBinding="{Binding Path=AccountGroupCode,

Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

Width="200"

IsReadOnly="False"

IsFilterable="False"

IsGroupable="False"

IsSortable="False"

IsResizable="False"

ShowFieldFilters="False"

ShowFilterButton="False"

ShowDistinctFilters="False">

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn x:Name="DescriptionColumn"

UniqueName="DescriptionColumn"

Header="{x:Static localProperties:Resources.Description}"

Width="*"

DataMemberBinding="{Binding Path=Description,

Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

IsFilterable="False"

IsGroupable="False"

IsSortable="False"

ShowFieldFilters="False"

ShowFilterButton="False"

ShowDistinctFilters="False">

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

<telerik:RadGridView.GroupDescriptors>

<telerik:GroupDescriptor Member="AccountCategory.CategoryName" />

</telerik:RadGridView.GroupDescriptors>

</telerik:RadGridView>

Note: In the image you'll notice that I have restyled to look of the GridView; however all I did was change brushes and did not introduce any new behavior.

Thanks in advance,
Steve

Bind dynamic data with CollectionView

Hi,
We have a requirement of binding the RadGridView with dynamic data. Whenever a new data comes in, I am assigning that data like this
public ICollectionView SampleView{get;set;}

// ViewModel where dynamic data gets updated.
this.SampleView =new CollectionViewSource { Source = dummyCollection}.View;

In XAML

<telerik:RadGridView Grid.Row="0"
  ItemsSource ="{Binding SampleView}" 
/>
This is the way I am binding the itemssource, but the UI is not getting bound.  Kindly help.

Unpinned panes have no content

Hi,

I'm using Prism and MEF to inject my views into RadPanes. Everything works great, with one exception... if a pane is unpinned (i.e. it is just a tab) when the application starts up, when I mouse over the tab or click to pin, the pane has no content. I can pin/unpin a pane that already has content without issue.

It's a reasonable guess that because the pane is not active on startup, no content is injected, and then it doesn't know to inject the content on mouse-over or when pinning that pane.

What event at the pane level can I track to know when a pane is now being displayed from a hidden state (both on mouse over, and on click)? In this way I think I could detect that a pane has no content and request a navigation to that region.

Alternatively, is there a way to have even hidden or unpinned panes be 'Active' so they load content?

More complex geometry from code

Hi!

We need to make a complex custom shape (please see attached png). It is composed of many different geometries and brushes. Plus, we have to draw it dynamically from code because it should be drawn according to some properties (nb of floors, number of Windows, etc...), so we c'ant use a xaml to describe the shape.

In our current home made diagram control, shapes derive from visualdrawing and we use the drawingcontext in conjunction with GeometryDrawing object.

Now, we are evaluating Telerik diagram control. Would this be possible? How would you achieve this ?

Any infos appreciated, thanks !

Row Details Editing

Hello,

I have GridView that has a RowDetailsTemplate specified.

I am trying to figure out how to force the row in a GridView into Edit Mode when the user is editing a property that is displayed in the Row Details template of that row. The GridView properly goes into Edit Mode when I edit a cell in the row, but not when I am in the Row Details.

Any help is appreciated.

Thanks.

On a button click, I want to be able to position the timeline to DateTime.Today.

Anyone have any suggestions?
