Could you help me to understand what I need to do in order to 'duration gross' field calculate average TimeSpan

I attached a couple of pictures what I did already.

Thanks in advance.

Hi everybody !

I have a radTreeView controller binding by self referencing data from a  programmatically build DataTable..

I define radtreeView ChildMember, ParentMember and DisplayMember properly, all looks fine.

on select event click like mouseclick for instance, I easily can get DisplayMember value using e.Node.Name or e.Node.text,  but I need to get the ChildMember value, and I can't find any way to find It.

A piece of help would be great !

Thanks in advance !

I am trying to implement shortcut key for my application and I try to use RadShortcuts to add into Shortcuts property of component such as TextBoxElement, ButtonElement. But it seems that the RadShortcuts does not work as I expected. 

For Ex: 

1. I create a RadShortcut with combination of Shift+LWin+M, there is no event fired.

2. I use Shift+M+LWin -> it works.

Any one know how to create RadShortcut as #1 ?

Thanks in advance,

I updated to 2016 Q1 from 2014.  In 2014, I had worked around the problem of the drop down closing whenever the user tried to click on a filter row by subscribing to the drop down closing event.  Here was the code for that event which worked great for me:

            If TypeOf sender Is RadMultiColumnComboBox Then
                rmc = sender
                If rmc.SelectedIndex > -1 Then
                    '--- if focus is on a row, then let popup close
                    'Console.WriteLine("clicked on: " & CStr(rmc.SelectedIndex))
                Else
                    '--- else, check mouse position and don't allow close if within popup window area
                    pt = rmc.EditorControl.TableElement.PointFromControl(MousePosition)
                    popTop = rmc.MultiColumnComboBoxElement.MultiColumnPopupForm.Top
                    popLft = rmc.MultiColumnComboBoxElement.MultiColumnPopupForm.Left
                    popHt = rmc.MultiColumnComboBoxElement.MultiColumnPopupForm.Height
                    popWd = rmc.MultiColumnComboBoxElement.MultiColumnPopupForm.Width
                    If pt.X >= popLft And pt.X <= popLft + popWd Then
                        If pt.Y >= popTop And pt.Y <= popTop + popHt Then
                            '--- should be click within window so leave it open
                            args.Cancel = True
                            rmc.Focus()
                        End If
                    End If
                End If

            End If 

Now, when a user clicks on the filter row, it opens the drop down so they can type in a filter but as before, they have to click on it twice to set the focus (a separate bug?). When they make the second mouse click with 2016Q1, I am now getting a null reference exception in Telerik.Wincontrols.UI.  I cannot even trap this error in a Try..Catch, it simply crashes the program.  Screenshot shows situation...user clicks drop down on Cust# field...clicks on filter row in customerName column, has to click again to set the focus and the POOF!

Thanks in advance for help.

Hello,

I would've thought there would be a simple way to do this, but having gone through the documentation I can't find anything.

What I want is that when there resides a data point on a chart which can be used to drill down to another chart, that when the mouse cursor hovers over that data point the cursor will change from an arrow to a hand.

https://docs.telerik.com/devtools/winforms/chartview/features/drill-down

Within the RadChartView object I can't find any events that would inform me of when the mouse cursor resides over a datapoint, and even when using the coordinates on the "MouseMove" event, I can't find anything within the API to translate the coordinates to a data point. 

Is there anyway to know when the mouse cursor is hovering over a datapoint?

Thanks!

I need to change the BackColor of the Tabs inside the PageViewElement of a Child row in a Gridview. I can access the PageViewElement itself, but how do I get to the Tabs' BackColor Property?

Hi,

Is there a way to allow the user to draw a rectangle and get all the data points within that rectangle?

Thanks

Hi,

I try to save the content of a simple RadForm to a Bitmap.The non client area of the form is not drawn at all (transparent value). If I disable Theming, it works.

Here is the code I used :
