Adjust columns in detail view

When using the detail view, the default column width is too wide. Is it possible to set the width before the dialog is shown?

I would also prefer that the column header text be left justified.

The first image shows how it looks now and the second image shows how I want it to look.

BoardView

Hello,

I'm trying to implement a (Kanban style) BoardView. It's similar to CardView (grouped cards, with drag&drop functionality), but i need a custom layout method: horizontal groups (columns), and vertical items (cards). So i was trying to inherit from ListView (like a CardView), but i cant override internal methods and properties.

I want to inherit from a theme-supported class (CardView/ListView ), not directly from radControl.

Any suggestions?

Thanks!

Enter Key Behaviour when Editing Cells

Hi,

I have a Grid with a number of read only columns and two editable columns and would like the ENTER key and TAB key to behave the same when editing data..

When I am editing a value in a cell and press TAB, focus skips over any read only columns in the row and moves to the next editable column. When I TAB off that, focus moves to the first editable column of the next row. This is desired behaviour.

When I am editing a cell and press ENTER though, focus moves to the next column whether it is read only or not. I have set EnterKeyMode to NextCell.

Is there any way to simulate the tab behaviour when the Enter Key is pressed?

Thanks,

Mark.

How can I show GridView title (caption)?

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.

ScatterLineSeries Point Labels

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

Set Layout Configurator default

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

Gridview not supporting Sort Descriptor

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.
