In fact the question is in the thread name. :) I couldn't find any information about how to do it. The only thing I found is that Grid Caption Text is not what I'm looking for.

Hello,

Is it possible to add labels to points in a ScatterLineSeries? I've been able to add labels to CategoricalDataPoints but not ScatterDataPoints. I noticed that on https://docs.telerik.com/devtools/winforms/controls/chartview/series-types/series-types there are labels for Line, Spline, Area, and SplineArea series, but not for Bar or Scatter.

I added a custom LabelFormatting event that gets called when I use a LineSeries with CategoricalDataPoints, but it doesn't run when I use a ScatterLineSeries with ScatterDataPoints. Here's some sample code I tested (in OpenEdge) and a screenshot of my results:

LabelFormatting method:

METHOD PRIVATE VOID myLabelFormatting(INPUT sender AS System.Object, INPUT e AS ChartViewLabelFormattingEventArgs):
   e:LabelElement:BackColor = System.Drawing.Color:White.
   e:LabelElement:ForeColor = System.Drawing.Color:Black.
   e:LabelElement:BorderColor = System.Drawing.Color:Black.
   e:LabelElement:Font = NEW Font("Segoe Script", 12, FontStyle:Regular).
   DEFINE VARIABLE element AS CartesianLinePointElement NO-UNDO.
   MESSAGE "Casting element..." VIEW-AS ALERT-BOX.
   element = CAST(e:LabelElement:Parent, CartesianLinePointElement).
    
   DEFINE VARIABLE dataPoint AS ScatterDataPoint NO-UNDO.
   MESSAGE "Casting point..." VIEW-AS ALERT-BOX.
   dataPoint = CAST(element:DataPoint, ScatterDataPoint).
    
   e:LabelElement:Text = STRING(dataPoint:XValue) + ", " + STRING(dataPoint:YValue).
END METHOD.

 

Sample code:

THIS-OBJECT:radChartView1:LabelFormatting:Subscribe(myLabelFormatting).       
 
DEFINE VARIABLE lineSeries AS ScatterLineSeries NO-UNDO.
lineSeries = NEW ScatterLineSeries().
lineSeries:DataPoints:Add(NEW ScatterDataPoint(1, 10)).
lineSeries:DataPoints:Add(NEW ScatterDataPoint(15, 15)).
lineSeries:DataPoints:Add(NEW ScatterDataPoint(5, 20)).
lineSeries:PointSize = NEW SizeF(8, 8).
lineSeries:ShowLabels = TRUE.
radChartView1:Series:Add(lineSeries).
 
radChartView1:BackColor = System.Drawing.Color:LightGray.
radChartView1:ShowLegend = TRUE.

 

Thanks,

Adam

Using code similar to this, is it possible for me to set the Layout Configurator to one of the options like "Default"? I'm not sure what I'd use for "doubleBufferedTableLayoutPanel1" or "filterDropDownList".

AddHandler Me.RadSaveFileDialog1.SaveFileDialogForm.Shown, AddressOf SaveFileDialogForm_Shown     
     
Private Sub SaveFileDialogForm_Shown(sender As Object, e As EventArgs)
        Dim dropDown As RadDropDownList = TryCast(Me.RadSaveFileDialog1.SaveFileDialogForm.Controls("doubleBufferedTableLayoutPanel1").Controls("filterDropDownList"), RadDropDownList)
        dropDown.SelectedIndex = 0
End Sub

I have Winform 2015 Q3 1104, I was on 933 and since the update, I can't open Property Builder on a GridView if there is a sort descriptor on it. I can remove it with the sort descriptions data operation, but if I add one again, I can't open the Property Builder.

It does the same on every radgridview in my project.

Is there a way to keep the ribbonbar tab selected when the ribbon is collapsed?  I am want to achieve the pageview's tabbing and page switching features along with the ribbonbar's ribbon formatting.  If collapsed, the ribbonbar doesn't appear to have a SelectedCommandTab value present.  I need to keep this property and the appearance of a selected tab when the ribbon bar is collapsed.

Is this possible, or is there a better solution?

Hello

I know that this question has been discussed many times, I have tried various solutions but I have a strange behavior that I can not correct.

I use a 4K 3840x2160 monitor, Visual Studio 2015, .net 4..7

I have a fairly large WinForms project with many forms and user controls.

In the development environment some of the forms or user controls are displayed in "readable" font sizes and other forms or user controls are displayed in very small fonts.

I set the autoscale property of the form to DPI and I set it to inherit to the use controls - I have tried to change this propertx to other values without any visible change.

I trust that the "final" application used on normal resolution displays (1920x1080 or smaller) will work properly but in teh develpment environment it's very uncomfortable to work with very small fonts.

Is there something I can do to correct this abnormal behavior ?

Thanks in advance

Pierre-Jean

Hello,

I am currently implementing the RadScheduler control where I have already replaced the AppointmentEditDialog and the EditRecurrenceDialog.

Could you point me in the right direction how to replace the message-dialog when you move/resize a single item of a recurrence appointment?

(See attached image)

 

Best regards

Patrick Vossen
