Hello,
I am trying to create custom ContainerShape which looks like the attached files.

1) Sample01.png file
In the header, I want to add the 'text' and 'collapsible' button.
For the Child area, I want to add text boxes, arrow image, and connections.
In the middle, I want to add a '+' button, where a user can drag & drop a shape into containerShape.

2) Sample02.png file
In the header, I want to add 'text' and two buttons('+' and 'collapsible').
For the Child area, I want to add two separate areas, where each area contains its child items.
'+' button for each area is for a user to drag & drop a shape into the corresponding area.

3) Sample04.png file
So my question is how can I customize the red outlined area in sample04.png
to create custom containerShape described in sample01.png and sample02.png.

Any help will be greatly appreciated.

Thanks.

[Solved] Changin cell style in telerik > 2020.1.115.45

Hi,

in 2018.2.515.45 version of telerik RadGridView I did:

var col = new GridViewDataColumn() { DataMemberBinding = new Binding(item.Name), Header = header };

col.CellStyle = new Style();

col.CellStyle.Setters.Add(new Setter(GridViewCell.FontWeightProperty, FontWeights.Bold));

MyRadGridView.Columns.Add(col);

to set the font of a certain column to bold. Now, after update to 2020.1.115.45 version this is not working any more. The content of this column is invisible.

I tried this:

col.CellStyle = new Style() { TargetType = typeof(GridViewCell) };

but no changes.

How can I add a setter to the style in new version?

How do i know connection contains point?

Hello,

I'm sorry to leave so many questions.

Here's the question.

I'd like to find out if the point above the diagram is within the connection.

Other DiagramItems, such as Shape, could calculate to Shape.Bounds.Contains(point).

However, the connection is a line, so if you calculate it as Bounds, there is a problem that i can't measure properly.

I want to get a bool value for the point above the connection or, if possible, within an interval between 1 and 5 around the connection line.

Connection.Geometry has a different position value and connection.Geometry doesn't have been activated by fillcontains or stalkcontains.

Main window doesn't get focus

Hello,

When I use a RadSplashScreen at the launch of my application, the application's main window doesn't receive focus and appears behind other windows. I've seen a reference to this type of behavior on another thread regarding RadWindow (https://www.telerik.com/forums/mainwindow-losts-focus-after-child-radwindow-is-closed), but the solution there doesn't seem applicable to this control.

I created a sample application (https://github.com/3milio/RadSplashScreenHidingMainWindow) with VS 2017 following your getting started guide. Mind trying it out and seeing if I'm missing a step? For me, when I hit F5 in the debugger to run it the splash screen appears on top of it but then when the main window gets instantiated it hides behind other programs.

Also, when I first cloned the repo and ran it in the debugger it didn't demonstrate this behavior. But any time after that, it did. That includes running it with the Release configuration, as well as simply running the .exe from Windows Explorer.

Thanks,

Emilio
