Hello,
I have defined my own GroupBox, that inherits the RadGroupBox.
If I apply a Theme, nothing happend.
Button, MaskedEditBox, CheckBox etc. works fine, but not the GroupBox.
Is this an known issue?
Regards
First, I'm new to Telerik Controls.
I'm trying to show a simple hierarchical class (some Properties and a List<T> with sub entries) in a RadGridView. I figured out I can use "AutoGenerateHierarchy" which works so far. But I'm having a real hard time to make it look how I need it. Especially for the sub entries. What ever I change in the Property Builder on "Template1" doesn't seem to have any effect. Also does it display a + even if the entry doesn't have sub entries.
I would appreciated if you could help me out with this...
Greetings,
I want the RadTimePicker to show only Time value , not date. How to do that ?
Thanks

Hello, I have tried modifying https://docs.telerik.com/devtools/winforms/ganttview/timeline/custom-timeline to have it do custom ranges, however when I run my copy I get a fully blank header. See attached for images.
My setting the custom behavior:
radGanttView1.GanttViewElement.GraphicalViewElement.TimelineStart = start; // Start is a DateTimeradGanttView1.GanttViewElement.GraphicalViewElement.TimelineEnd = end; // End is a DateTimeradGanttView1.GanttViewElement.GraphicalViewElement.OnePixelTime = TimeSpan.FromMinutes(0.0025);radGanttView1.GanttViewElement.GraphicalViewElement.TimelineRange = TimeRange.Custom;var behavior = new WarehouseTimelineBehavior { Start = start, End = end };radGanttView1.GanttViewElement.GraphicalViewElement.TimelineBehavior = behavior;And my Behavior class:

Hey guys, I'm trying to add a QuickStart(TextBox with Autocomplete) to the Title Bar, like visual studio 2017. I've tried adding a RadTextBoxElement, but I couldn't even enter text on it, any help? But of course I wanna it beatiful, like Visual Studio, changing border colors and back color. I've attached how it is on VS and how it is on mine.
The button is a RadButtonElement.
Hello Telerik Team !
I currently try to achieve something similar to the attached picture.
Maybe I took the wrong direction, by using a MaskedEditBox with a DateTime MaskType, I am trying to add an adjacent button picture to open a calendar, and also a drop down button with several standard choice.
By editing UI Elements I notice the presence of a StackLayoutPanel with LightVisualButtonElement, I put both Visibility to Visible and add a little calendar icon image.
I can see It on Visual Studio, but the icon does not appear when I launch the program, and also I don't have any idea what kind of event I need to add if I succeed in showing the icon to open a calendar control to select my date.
So maybe I took a wrong direction by using this controls ?
Any help or suggestion would be highly welcome
Thanks in adavnce

Hi there,
I've used Telerik grid inside an application.
I wanna to do something when the user changes the order of column groups (column group 1 and column group 2) by dragging them using a mouse. but I didn't find any solution for this.
So is there any event to detect reorder change for "column group"?

I want users to be able to modify columns width, order, pinned state, ... But at the same time, I have two grids in the same form one above the other and I would like to sync layout of both.
I have tried to use somthing like this, but it is not working:
foreach (var col in this.grid1.Columns)
{
this.grid2.Columns.Add(col);
}
