Hi,

I create a control using a RadScheduleView and a weekview definition. People using my control pass me a collection of not readonly slot and I want to set the rest of the view as readonly. I want to know if there is a mechanism for doing this in the control.

Thank's
Alain

Hi,

I created a UserControl based on a ScheduleView. My UserControl offer an OnCanDrop event so I implemented a DragDropCustomBehavior to reach my goal. In the CanDrop override method of my DragDropBehavior, I don't want to raise my event when I'm over the appointment I'm dragging...

Thank's
Alain

Hello, I would like to achieve the red validation pop-out message as shown in the 2nd picture from the link above. All my other codes are working, except for red pop-out message. Is there anything I'm overlooking? Below are my codes:

​

I have a datepicker in a grid column, and when the cell changes, it does not call my grid event "OnRowEditEndedCommandCommandExecuted". How do I make this happen? Thanks.


          <telerik:GridViewDataColumn  Header="Date Filled" Width="100" >
                    <telerik:GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <telerik:RadDatePicker SelectedValue="{Binding DateFilled, Mode=TwoWay}"/>
                        </DataTemplate>
                    </telerik:GridViewColumn.CellTemplate>
                </telerik:GridViewDataColumn>

Is it possible to control the location of the window after it has been minimized? Currently it always shows right above the start bar. 

Hi!

I am trying to create a tree diagram in the code behind. The problem is the connectors are segmented to much. Is there a way to adjust segmentation? Attached you can find the screen grab.

Thanks,

I'm seeing two different validation error messages with different styles when I hover the mouse over slightly different portions of the hotspot. Is there a way I can get rid of the second one - the one I did not set?

My goal is to allow clients to place markers on a graph. They would like to select points of interest which are usually a local maximum on a LineSeries. The idea would be to use the ChartTrackBallBehavior to place custom annotations on the chart using the method described in the following post:

http://www.telerik.com/forums/trackball-position-hold-on-mouse-click

Selecting a local maximum is quite hard especially with the kind of mice our clients use (OzuPad). That is why we would like the TrackBall to snap to a local maximum. Unfortunately the only type of snap is snap to the closest point. Do you have any idea how we should implement snapping to a local maximum? Not using the ChartTrackBallBehavior is fine, but it would be a shame to let go of the features it already provides.
