Display validation error in tooltip for gridview cell

I would like to display the validation error in the tooltip of a radgridview cell so when the user hovers over the cell the validation message will be displayed when the grid's RowIndicatorVisibility="Collapsed". I can see the error when hovering over the right top corner of the cell but that is very small and our users aren't sophisticated. I've tried creating a style but its not working.

Thank you for your help.

RadGeometryDropDownButton DropdownContent for export command disabled

We are using the OrgChartDiagram to show the organization hierarchy in our application. To export the diagram, we used the RadGeometryDropDownButton control with two options PNG and BMP. We are using the telerik:DiagramCommands.Export command is used for that purpose. Sometimes, the options are disabled when we go to other page and back. We need to reload the page to get that option enabled. When the export command remove from the code, the options are enabled.

Please help us to resolve.

See below the code for your reference. ElementName in Command target is the org chart control name.

How can we solve this problem?

Thanks a lot

[Solved] Get a ganttTask in SchedulingResizeBehavior class

Hi,

I'm using a RadGanttView control and need some help with the next problem: I have created a CustomResizeBehavior class that inherits SchedulingResizeBehavior class to customize a resizing behavior. I want to deny the resizing of some gantt tasks. So I need to get the task that is resized on the GanttChart and override CanResize method in some way. More particular: I have a couple of classes that inherit IGanttTask, and for some of them I need to restrict resizing. That's why I need to have an access to the gantt task in the CanResize method. Is there any way to get it?

Thank you,
Natalia Novosad
