(RadGridView)(EditorRequired)(RadDateTimeEditor) How to define the Date format?

Background:

I have a gridview column subscribing to EditorRequired event.
In the EditorRequired function, it will either prompt DropDownList or RadDateTimeEditor.

(Please refer attached for sample project)

 private void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
        {
            if (this.radGridView1.CurrentColumn.Name == "Value" && this.radGridView1.CurrentRow.Cells[2].Value.ToString() == "DropDown")
            {
                RadDropDownListEditor editor = new RadDropDownListEditor();
                RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;
                element.DropDownStyle = RadDropDownStyle.DropDownList;
                element.AutoSizeItems = true;
                var selection = this.radGridView1.CurrentRow.Cells[3].Value.ToString().Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).ToList();
                element.DataSource = selection;

                e.Editor = editor;
            }
            else if (this.radGridView1.CurrentColumn.Name == "Value" && this.radGridView1.CurrentRow.Cells[2].Value.ToString() == "Date")
            {
                RadDateTimeEditor editor = new RadDateTimeEditor();
                editor.CustomFormat = "dd-MMM-yyyy";
                e.Editor = editor;
            }
        }

Question:

How to define the Date format?

I have tried to set the CustomFormat but the format remains as shown in the screenshot above.

 RadDateTimeEditor editor = new RadDateTimeEditor();
                editor.CustomFormat = "dd-MMM-yyyy";
                e.Editor = editor;

Can't Drag and Drop RadCallout onto a Form

I'm trying to drag and drop RadCallout to an existing Form Designer, and while I don't get any errors and it appears that it drags and drops, the control doesn't remain on the form and does not appear in the Components Tray either. I do not have a problem adding other Rad controls, but Callout doesn't seem to work. Will it only work with a Rad Form? Or is there a prerequisite I should know about? Do I need to install something so that the Designer can properly display it?

I'm using Visual Studio Professional 2022 version 17.5.5 with Telerik UI for WinForms Extension 2023.1.313.33.

Thanks in advance!

How to get radtreeview drag and drop event to handle the to get source and destination full path node ?

Hi,
1. How to get radtreeview drag and drop event to handle to get source and destination full path node using vb.net. I tried but i can get both source and destination as same node. I provide treeview node sample structure.

Family
----Father
---Son1
---Son2
----Mother
---Son3
---Son4

Here i drag and drop Son4 under the Son1, so i need to get source as Family/Mother/Son4 and destination as Family/Father/Son1/Son4.

2. How to restrict to drop nodes in level 1(Family) and level 3 (Son1,Son2,Son3,Son4), i need to move nodes Son1,Son2,Son3,Son4 under Father and Mother node, not to create child node under Son1,Son2,Son3,Son4, I mean move Son2 above Son1, same like Son4 move above Son3 and also move Son3 or 4 move to below Father node, same like Son1 or 2 move below Mother as child node.

Please reply asap.

Spreadsheet horizontal scrolling behaviour

When I load data into my sheets, where there are columns which have a lot of data (long descriptions of things) and I use 'autoFitWidth to make things look sensible, I end up with some very wide columns, as expected.

Where a column is wider than the viewable area, left and right scroll often don't do anything: the sheet still shows one column. It seems to want to show all of a column, so after a while, it jumps to the next wide column.

(zipped video below)

This is strange behaviour, and also means that my users can not figure out how to re-size one of these wide columns, and then use word wrapping to make it easier to read.

Have I done something bad to my data to make it do this ? Or is there a setting somewhere to make the scrolling smooth?

Thanks
