Hello Team,

I have updated the latest Telerik Version(2016 Q3) and after update I am seeing "True" value instead of "And/Or" in the Filter. Please look at the Screenshot for more information.

Placing Docking control in another Docking control

Hi,
if I place a Docking control in another Docking control i recive (only at runtime) this error:
"Placing Docking control in another Docking control is not supported in the current version. You can disable this error by setting the AllowUnsafeMode property of the inner RadDocking control."

When are you planning to implement and release this feature?

Thanks.

Is there an easy way to turn off full row selection highlighting?

The problem that we're having is that we have context menus for individual tree items and a context menu for the tree itself.

A right-click on the empty highlighted area next to a selected item in the tree brings up the tree view context menu instead of the item context menu, which is a bit confusing to the user.

We'd prefer to be able to have the selection highlight only cover the actual item contents, not the empty space to the right of the item.

Exception for filter on byte columns

Hi,

I added a GridColumn in binding with byte property, when I try to filter with value greater thant 255 I receive an exception.

Thi is my grid, my column "Ultima Revisione" is a byte,

When I try to filter (for example "106", see attached screenshot), it's all ok, but if I add "8", I receive an overflow exception, because byte can't compare with a value 1068.

I thought the filter handles all types of primitive variables....

How can I resolve this issue? (Do not tell me to do a string variable alternative ...)

<telerik:RadGridView x:Name="radGridView" Style="{StaticResource ListStyle}"

ItemsSource="{Binding Items}" MouseDoubleClick="RadGridViewMouseDoubleClick"

SelectedItem="{Binding SelectedItem,Mode=TwoWay}"

IsLocalizationLanguageRespected="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Codice}" Header="Codice"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Descrizione}" Header="Descrizione"/>

<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding Ricambio}" Header="Ricambio"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding CodiceValuta}" Header="Valuta"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding UltimaRevisione}" Header="Ultima Revisione"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding UltimaRevisioneReference.InizioValidità, StringFormat=\{0:d\}}" Header="Inizio Validità"/>

</telerik:RadGridView.Columns>

</DataTemplate>

</Grid>

The code above shown is for datatemplate and RadCombobox in UserControl. In DataTemplate I am binding the Text Property of textblock with one of the dependencyProperty on the usercontrol and the datacontext of combobox is not the usercontrol another viewmodel.

I have tried the code in this post also.

Event before the grid is filtered

I am using DataFilter and its source is Bind to the Grid, I don't want to use the unbound mode because then I will have to populate everything. I am using rest service to get all the data and I want to do the filtering also on the server side.

- User open the window

- I make a rest request to get the data and populate the grid

- User add a filter

- I am listening for the collection changed and item changed event

- I loop through all the filters and send a request to get the filtered data

The problem is that DataFilter also filters the grid on the client side, so If my rest request takes time the grid items source is updated twice, one from the data filter and another one when rest returns the data

Is there any preview event or any other way to tell datafilter ot not filter the grid
