Hi,
I have a requirement to allow the user to drop an object onto the grid even if the grid has no rows. However my callback methods for the AddDragOverHandler and AddDropHandler aren't called if I'm not over a row. How can I get called back in this case?
Thank you

Losing GridViewSelectColumn on binding the grid to a DataTable.

I'm using the RadGridView and have its DataContext bound to a DataTable. By doing so, I'm losing the GridViewSelectColumn which is my first column in the grid. How can I bound my data table to a RadGridView and yet have a GrdiViewSelectColumn as my first column in the grid?

Thanks.

StaticResource in Teleric Theme

Hi all,
I want to do the following behavior in my program.
I have a GridView and below form, which is still visible. I need to change the background when the form gets focus. Standard background is gray, and if form get the focus to look the same(background) as the selected row in the DataGrid. It is not difficult, but if I change the main theme from SummerTheme to Office_SilverTheme, I have a complicated background to change.

My query is as follows.
Can I use this
<Setter Property="Background" Value="StaticResource GridViewRowSelectedBackground}" />
And call value in TelericTheme.

If I change the StyleManager.ApplicationTheme in the future, I will get right background.

Thank you for the tip.

My definition style in Themes/Generic.xaml

<LinearGradientBrush x:Key="GridViewRowSelectedBackground" EndPoint="0.5,1" StartPoint="0.5,0">

<GradientStop Color="#FFFFCA5D" Offset="1"/>

<GradientStop Color="#FFFFDC9C" Offset="0"/>

</LinearGradientBrush>

<Style x:Key="Form_Style" TargetType="Border" >

<Setter Property="BorderBrush" Value="White" />

<Setter Property="BorderThickness" Value="2" />

<Setter Property="Padding" Value="1" />

<Setter Property="Margin" Value="1" />

<Setter Property="CornerRadius" Value="5"/>

<Setter Property="Background" Value="{StaticResource Form_Background}" />

<Style.Triggers>

<Trigger Property="IsKeyboardFocusWithin" Value="True" >

<Setter Property="Background" Value="{StaticResource GridViewRowSelectedBackground}" />

</Trigger>

</Style.Triggers>

</Style>

ComboBox Column not displaying new property value in view mode

I have the following comboboxcolumn that is bound to a collection of strings. The DataMemberBinding points to a property in the object model. This property gets updated in another part of the system, but the comboboxcolumn does not reflect the new value in view mode. As soon as I click on the field, the combox displays the updated value. How can I get it to update in view mode?

<telerik:GridViewComboBoxColumn Header="M"

DataMemberBinding="{Binding SummaryGroupDetail.MisclassifiedType, Mode=TwoWay, NotifyOnSourceUpdated=True}"

UniqueName="MisclassifiedType"

ItemsSourceBinding=

"{Binding Path=DataContext.MisclassifiedTypes, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"

/>

Empty RadGridView breaking on paste

RadGridView breaks when you have no data in it and you try and paste. I get a DataGrid_DisplayIndexOutOfRange exception. Here is an example:

<Window x:Class="TestTablePaste.MainWindow"

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

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

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<Grid>

<telerik:RadGridView>

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu>

<telerik:RadMenuItem Header="Paste" Command="ApplicationCommands.Paste"></telerik:RadMenuItem>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</telerik:RadGridView>

</Grid>

</Window>

I was wondering if this is a known issue and if there was a work around.
