Open Context Menu on MouseMove over Selected Row in DataGrid

[Nick]

Hi there,

 So there is a way to open Context menu on specific event. (http://www.telerik.com/help/silverlight/radcontextmenu-features-opening-on-specific-event.html) That is really useful.

Now I want to do the same but only if control is in focus. My example:

I have DataGrid control with it's own template. I also have DataGridRowTemplate in place. DataGridCellsPresenter have context menu. Right now I have EventName="MouseMove" I want to open context menu only if mouse move over selected row. Currently it will open context menu fo any row even if it is not selected.

                       <dataPrimitives:DataGridCellsPresenter x:Name="CellsPresenter" Grid.Column="1" dataPrimitives:DataGridFrozenGrid.IsFrozen="True">
                           <telerik:RadContextMenu.ContextMenu>
                               <telerik:RadContextMenu IconColumnWidth="36" ShowDelay="0:0:1" EventName="MouseMove"  >
                                   <telerik:RadMenuItem Header="Add/Edit Tag" Command="{Binding ContextMenuClick}" CommandParameter="Add/Edit" >
                                       <telerik:RadMenuItem.Icon>
                                           <Image Source="/Scorecard.Common.Silverlight.Controls;component/Resources/TagAdd.png" Stretch="Fill"/>
                                       </telerik:RadMenuItem.Icon>
                                   </telerik:RadMenuItem>
                                   <telerik:RadMenuItem Header="Remove Tag" Command="{Binding ContextMenuClick}" CommandParameter="Remove" >
                                       <telerik:RadMenuItem.Icon>
                                           <Image Source="/Scorecard.Common.Silverlight.Controls;component/Resources/TagRemove.png" Stretch="Fill"/>
                                       </telerik:RadMenuItem.Icon>
                                   </telerik:RadMenuItem>
                               </telerik:RadContextMenu>
                           </telerik:RadContextMenu.ContextMenu>
                       </dataPrimitives:DataGridCellsPresenter>

any suggestions?

Hello Nick,

Unfortunately, you need a custom logic in order to accomplish this. There is no specific event that will be fired when the mouse moves over a selected element. I would suggest you to handle the MouseMove event and check is the row is selected. Then you can open the RadContextMenu.

I hope this helps.

All the best,
