wonder if you can help with the simpler way to reapply filters programmatically. I have found so far only 1 solution:

IFilterDescriptor[] filterDescriptors = new IFilterDescriptor[_gridView.FilterDescriptors.Count];
_gridView.FilterDescriptors.CopyTo(filterDescriptors, 0);
_gridView.FilterDescriptors.Clear();
_gridView.FilterDescriptors.AddRange(filterDescriptors);

is there more elegant method?

Cheers, Igor

Themes

Hello Telerik,
I've got two question about theming... In my application I've curertly defined 2 brush for a RadGridView alternate row choosing the color similar to OfficeBlu theme, now that I changed the theme I have to find the colors again..is there a way of getting a theme default background color?

Second question: I've added a stackpanel for having a whole Menu bar as

<Grid Grid.Row="0" Background="#FFF0F0F0">

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*"></ColumnDefinition>

</Grid.ColumnDefinitions>

<StackPanel Orientation="Horizontal" Grid.Column="0" >

<local:MenuView x:Name="Menu" cal:Bind.Model="{Binding Menu}">

</local:MenuView>

</StackPanel>

<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="5,0,5,0" Grid.Column="1" Background="#FFF0F0F0" cal:Action.Target="{Binding}">

<TextBlock x:Name="LoggedUser" Background="Transparent" Foreground="#242881" FontStyle="Italic" FontWeight="Bold" ></TextBlock>

<TextBlock Name="TextBlockWithHyperlink" Text=" Info" Background="Transparent" cal:Message.Attach="[Event PreviewMouseDown] = [Action ShowInfo()]" cal:Action.TargetWithoutContext="{Binding}" >

</TextBlock>

</StackPanel>

</Grid>

The same problem here...how do I tell pick the telerik:RadMenu default background color and apply it to my stackpanel?

Thanks
Paolo

Problem filtering date

When I try to filter my source by a datetime field, I get the default date picker. I enter a date or select from the calendar but my result grid doesn't show the records that correspond with that date. Could it be because the editor is looking at the date only and my underlying value has both date & time? How do I get around this if this is in fact the issue?

[Solved] RadDataFilter Annotations drawback

Hi,

I would like to be able to set which fields are available for datafiltering on the RadDataFilter. As i understand, this can be done using annotations. However i find the use of annotations cumbersome. I use the RadDataFilter to filter data in a RadGridView. The RadGridView is boud to a collection in the Viewmodel. Now in order to specify which fields are available for datafiletring, i would have to annotate the public fields of my viewmodel. I think this is a violation of seperation of View and Viewmodel. Moreover, if i have diferent views using the same viewmodel with a RadDataFilter and i wish to have different fields available for filtering in each view, then this cannot be done.

In my honest opnion, which fields can be filtered, and what their caption is in the RadDataFilter should be specified in a collection of the RadDataFilter itself (much as the columns collection in the RadGridView).

If you think i going the wrong way here please let me know.

Kind regards,
Ronald Steenbergen

DropDownButton with RadContextmenu and keyhandling

Hi,

I am using a DropDownbutton with a RadContextmenu. When using Accesskey on the RibbonView/DropDownbutton/RadContextmenu. De access keys don't show on the submenu of the RadContextmenu. A made a sample to demonstrate this:

<Window x:Class="WpfRibbonMenuKeys.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="MainWindow" Height="350" Width="525" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">

<Grid>

<telerik:RadRibbonView Name="radRibbonView1" VerticalAlignment="Top" telerik:KeyTipService.IsKeyTipsEnabled="True">

<telerik:RadRibbonTab Header="RibbonTab" telerik:KeyTipService.AccessText="H">

<telerik:RadRibbonGroup Header="SomeGroup" telerik:ScreenTip.Title="SomeGroup" DialogLauncherVisibility="Collapsed" >

<telerik:RadRibbonDropDownButton Text="DropDown"

Size="Large"

telerik:KeyTipService.AccessText="S">

<telerik:RadRibbonDropDownButton.DropDownContent>

<telerik:RadContextMenu >

<telerik:RadMenuItem Header="Test1" telerik:KeyTipService.AccessText="1"/>

<telerik:RadMenuItem Header="Test2" telerik:KeyTipService.AccessText="2">

<telerik:RadMenuItem Header="Test2.1" telerik:KeyTipService.AccessText="21"/>

<telerik:RadMenuItem Header="Test2.2" telerik:KeyTipService.AccessText="22"/>

<telerik:RadMenuItem Header="Test2.3" telerik:KeyTipService.AccessText="23"/>

</telerik:RadMenuItem>

<telerik:RadMenuItem Header="Test3" telerik:KeyTipService.AccessText="3"/>

</telerik:RadContextMenu>

</telerik:RadRibbonDropDownButton.DropDownContent>

</telerik:RadRibbonDropDownButton>

</telerik:RadRibbonGroup>

</telerik:RadRibbonTab>

</telerik:RadRibbonView>

</Grid>

</Window>

The menuitems Test2.1, Test 2.2 and Test 2.3 don't show access keys. Also when having used access keys, it is not possible to use the arrow keys to navigate through the contextmenu. So when using Alt-H-S-2, in the sample, the submenu is opened, but further keyhandling is not respected.

Regards,
Ronald
