Reorder issue with Multiple grid

[Pradnya]

Hi,

I have two grid view on same page I have Implemented reordering functionality to both grid uisng RowReorderBehavior,GridViewDataControlExtensions, BeginningDragEventArgs etc classes but In that scenario I am getting following error 
Message : "Value does not fall within the expected range."

StackTrace:

   at MS.Internal.XcpImports.CheckHResult(UInt32 hr)
   at MS.Internal.XcpImports.Collection_AddValue[T](PresentationFrameworkCollection`1 collection, CValue value)
   at MS.Internal.XcpImports.Collection_AddDependencyObject[T](PresentationFrameworkCollection`1 collection, DependencyObject value)

   at System.Windows.PresentationFrameworkCollection`1.Add(T value)
   at Configuration.Reorder.RowReorderBehavior.AttachDropPositionFeedback()

Class Name: RowReorderBehavior
Method Name: AttachDropPositionFeedback

It works for single gridview but it throw an exception when I implement reordering for more than one gridview

Please help me to resolve this issue.

Thanks-

Hi,

 I have tested the row reordering between two GridViews using the source code at this online demo. My test project does not throw such an exception. I do not see the "AttachDropPositionFeedback" method name though and I am not sure what the problem in your implementation would be.

Would you please share more details on your exact implementation?

Hi Didie,

Thank you for ur reply

I am doing reording on two separate grid not a row reordering between two GridViews

First Grid:

 <telerik:RadGridView x:Name="teamembersGridView" RowIndicatorVisibility="Collapsed" toolkit:DockPanel.Dock="Top" Margin="0,7,0,0" ShowGroupPanel="False"
                                     ColumnWidth="*" CanUserFreezeColumns="False"
                                     AutoGenerateColumns="False" AlternateRowBackground="WhiteSmoke" AlternationCount="2"
                                     ItemsSource="{Binding Path=Team.FlexTeam.TeamMemberCollection, Mode=TwoWay}"
                                     CanUserResizeColumns="False" telerikDragDrop:RadDragAndDropManager.AllowDrop="True"
                                     VerticalAlignment="Top" HorizontalAlignment="Stretch">
                    <i:Interaction.Behaviors>
                        <example:RowReorderBehavior x:Name="memberReorderBehavior" DragCueItemTemplate="{StaticResource DraggedItemTemplate}"
             DragCueTooltipContentTemplate="{StaticResource DraggedItemTemplate}"/>
                    </i:Interaction.Behaviors>

                    <telerik:RadGridView.RowStyle>
                        <Style TargetType="telerik:GridViewRow">
                            <Setter Property="telerik:RadDragAndDropManager.AllowDrag" Value="True" />
                        </Style>
                    </telerik:RadGridView.RowStyle>
</telerik:RadGridView>

Second Grid:

 <telerik:RadGridView x:Name="managerGridView" RowIndicatorVisibility="Collapsed"  Margin="0,-1,0,0" ShowGroupPanel="False"
                                     ColumnWidth="*" telerikDragDrop:RadDragAndDropManager.AllowDrop="True"
                                     AutoGenerateColumns="False" AlternateRowBackground="WhiteSmoke" AlternationCount="2"
                                     ItemsSource="{Binding Path=Team.FlexTeam.TeamManagerCollection, Mode=TwoWay}"
                                     CanUserResizeColumns="False" BorderThickness="0"
                                     VerticalAlignment="Top" HorizontalAlignment="Stretch">
                    <i:Interaction.Behaviors>
                        <example:RowReorderBehavior x:Name="ReorderBehavior" DragCueItemTemplate="{StaticResource DraggedItemTemplate}"
             DragCueTooltipContentTemplate="{StaticResource DraggedItemTemplate}" />
                    </i:Interaction.Behaviors>

                    <telerik:RadGridView.RowStyle>
                        <Style TargetType="telerik:GridViewRow">
                            <Setter Property="telerik:RadDragAndDropManager.AllowDrag" Value="True" />
                        </Style>
                    </telerik:RadGridView.RowStyle>

</telerik:RadGridView>

Hello Pradnya,

 I have attached a sample project showing row reorder in two grids. Please check how it works.

what about full orange line that where we can add the row?

Which is not visible using your project.

Thanks-

Hi,

 I am not sure what is the orange line that you talk about. May you please clarify?
