I have a grid that I only ever want to show a subset of data items. I want the user to be able to play around with the filters, so I've created a CollectionView based on the original collection that has the permanent filter set. This CollectionView is set as the grid's ItemsSource so that the permanent filter and the user defined filters (FilterCollection) are kept separate.

However, I get an index out of bounds exception when adding items to the original collection. It looks like this is because the INotifyCollectionChangedEventArgs are specifying an index that is present in the original collection, but too high once the CollectionView filter has been applied.

Is this a strategy that should work and I'm missing something, or does anyone know of a better way to have a filter always set on the grid, despite calling FilterCollection.Clear() (my fallback strategy is to now create a FilterDescriptor to do the same job and re-add it every time I clear the filters).

Property to Control Column Drag and Drag Behavior

Hi,

As per my observations on RadGridVIew, i found column drag and drop is allowed by default.

Is there any property which controls the behavior of column drag and drop?

Thanks,

Ignore F2, Del, Ins key presses

How can I get a RadGridView to ignore F2, Del, Ins if it has keyboard focus? I have CommandBindings defined to handle these key presses and would like to have these CommandBindings executed. I don't want to ignore all keyboard input in the RadGridView however as I'd still like to navigate the rows in the RadGridView with arrow keys.

RadGridView drag multiple items

I am using the drag and drop manager along with the RadGridView to drag one or more items from the RadGridView. This was working fine in previous versions, but the latest 2010.2.714.40 doesn't seem to work any longer. I looked at the demos and it didn't work with multiselect and then dragging either. Did something change that I am not aware of, or did this just break? Thanks!

Error when compiling a simple project

Hello

I have downloaded RadControls_for_WPF_35_2010_2_0714_TRIAL and when I try to run a simple project including a RadGridView I got the following error:

Cannot resolve dependency to assembly cause it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event. Line 66 Position 10.' C:\Users\JORGE\Documents\Visual Studio 2008\Projects\Colonial3\Proveedores\Proveedores\UCDatosProveedor.xaml 66 10 Colonial3

The error points where the RadGridView is declared

<telerik:RadGridView x:Name="ProveedoresGridView" Margin="0"

IsReadOnly="False" CanUserFreezeColumns="False" CanUserInsertRows="True"

SelectionMode="Single" AutoGenerateColumns="False" IsFilteringAllowed="False" ShowGroupPanel="False" VerticalAlignment="Top" MaxHeight="768">

I hope you can help me

Best regards

TreeListView using XML

There is probably a simple answer to this, however I am a designer and have had no luck finding an answer to this via google or the support pages.

I am needing to use a RadTreeListView to show the following heirarchy:-

Calculation Set 1
- Calculation 1
  - Condition 1
- Calcualation 2
  - Condition 2
- Calculation 3
  - Condition 1
Calculation Set 2
- Calculation 4
  - Condition 1

Here is my proposed XML:

<?xml version="1.0" encoding="utf-8"?>

<Calculations>

<Calculation_Set Name="Calculation Set 1">

<Calculations>

<Calculation Name="Calculation1">

<Conditions>

<Condition Name="Condition 1"/>

<Condition Name="Condition 2"/>

<Condition Name="Condition 3"/>

</Conditions>

</Calculation>

<Calculation Name="Calculation2">

<Conditions>

<Condition Name="Condition 4"/>

<Condition Name="Condition 5"/>

</Conditions>

</Calculation>

</Calculations>

</Calculation_Set>

<Calculation_Set Name="Calculation Set 2">

<Calculations>

<Calculation Name="Calculation2">

<Conditions>

<Condition Name="Condition 6"/>

<Condition Name="Condition 9"/>

<Condition Name="Condition 12"/>

</Conditions>

</Calculation>

</Calculations>

</Calculation_Set>

</Calculations>

Can I get some help with the creation and binding?
