OpenAccess with DataForm

I'm new to Open Access, WPF and XAML.
My problem is I'm using an OpenAccess reverse-modelled table as the source for a WPF DataForm.
Everything works great as long as I 'Edit' rows but...
- can't Add (button is disabled)
- can't Delete (button is disabled)
- can't Cancel an edit (button is disable)
Committing an Edit works great. Navigation works Great.

Am I missing a setting in my Model, WPF or in XAML?

Thanks...

Is there a Command for the RadTileList

Hi,

i would like to use the RadTileList for the selection of single files from a Recently Used File list. How can I attach a command which gets executed when the users selects a tile?

I know that in the way Modern UI works there should be a separate action list with all the available actions. I just want that a single action is executed.

Right now I am using a separate button which is not intuitive especially within a touch based UI.

Regards,
Peter

Override default cell context menu with autogenerated columns

I've searched for a while but cannot seem to find a clear answer that works for the issue. I have a datagrid that is entirely auto generated. To this I added a context menu for right clicks when the cell is not in editable mode (see below). I would like to use the same menu when the cell is in edit mode i.e. I want to override the default context menu. I've tried various options including adding a CellEditTemplate in the code behind but this does not work because I need to reference the instance of the context menu in a non static (not sealed) context and templates only appear to want to work in a static/sealed context. What should I be doing?

<telerik:RadGridView x:Name="dataGridView" Margin="5,10,5,5"

AutoGenerateColumns="True"

AutoGeneratingColumn="DataGridView_AutoGeneratingColumn"

...other options....>

<telerik:RadGridView.ContextMenu>

<ContextMenu x:Name="gridContextMenu">

<MenuItem x:Name="clearCellMenuItem" Header="Clear Cell" />

<MenuItem x:Name="clearRowMenuItem" Header="Clear Row" />

<MenuItem x:Name="clearAllMenuItem" Header="Clear All" />

<Separator x:Name="separatorMenuItem" />

<MenuItem x:Name="copyMenuItem" Command="Copy" Header="_Copy" />

<MenuItem x:Name="pasteMenuItem" Command="Paste" Header="_Paste" />

</ContextMenu>

</telerik:RadGridView.ContextMenu>

</telerik:RadGridView>

Thanks

How to set DataTemplate of HierarchyChildTemplate (Code)

Hello,

I was trying to build up the DataTemplate for the HierarchyChildTemplate in my code.

As example the one from the online documentation http://www.telerik.com/help/wpf/gridview-how-to-access-child-gridview.html

<telerik:RadGridView Name="gridView" ItemsSource="{Binding Person}">

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition />

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<telerik:RadGridView ItemsSource="{Binding Children}" Name="childGrid" ShowGroupPanel="False" />

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

</telerik:RadGridView>

I tried something like:

gridView.HierarchyChildTemplate =

new DataTemplate(

new RadGridView

{

ShowGroupPanel = false,

IsReadOnly = true,

ItemsSource = new Binding("Children")

});

But i set the dataType in that constructor and not same property like in the xaml. What's the property i need to set?

Thanks.

I use the 2012.2.0912.35 version of telerik components on Framework 3.5.

Can you help me with this ?

Filter pop up window

Hi,

Is there a property to control the size of the filter window?. The buttons at the bottom (i.e. Clear Filter) as not visible. It appears that there are to many item shown in the list with the check boxes. I am using a split screen with the gridview getting about half the space. If I give the grid more screen space it works ok. Of course this is not acceptable. For your information I am using a Dynamic Class Object for ItemsSource and creating the columns programatically.

Thanks
Rich
