//adding 8 columns to DGV programmatically
....
//make just 6 column in a group format
ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();
dataGridView1.ViewDefinition = view;
view.ColumnGroups.Add(new GridViewColumnGroup("morning));
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows[0].Columns.Add(this.dataGridView1.Columns["MrnngEnt"]);
view.ColumnGroups[1].Rows[0].Columns.Add(this.dataGridView1.Columns["MrnngExit"]);
view.ColumnGroups.Add(new GridViewColumnGroup("evnng"));
view.ColumnGroups[2].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[2].Rows[0].Columns.Add(this.dataGridView1.Columns["EvnngEnt"]);
view.ColumnGroups[2].Rows[0].Columns.Add(this.dataGridView1.Columns["EvnngExit"]);

RadGridView with Hierarchy in Winforms

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...

Header of graphical view in 5 minute increments

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 DateTime

radGanttView1.GanttViewElement.GraphicalViewElement.TimelineEnd = end; // End is a DateTime

radGanttView1.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:

MaskedEditBox button

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
