Please refer to the attached sample project and follow the steps illustrated in the attached gif file.

Workaround: initialize a new RadDateTimePicker every time you toggle the checkbox:

    Dim location As Point
    Sub New()

        InitializeComponent()
        location = Me.RadDateTimePicker1.Location 
    End Sub
    Private Sub RadCheckBox1_ToggleStateChanged(sender As Object, args As Telerik.WinControls.UI.StateChangedEventArgs) Handles RadCheckBox1.ToggleStateChanged
        Me.Controls.Remove(Me.RadDateTimePicker1)

        Me.RadDateTimePicker1 = New RadDateTimePicker()
        Me.RadDateTimePicker1.Parent = Me
        Me.RadDateTimePicker1.Location = location
        With RadDateTimePicker1
            Dim i_calendar As RadDateTimePickerCalendar = TryCast(.DateTimePickerElement.GetCurrentBehavior(), RadDateTimePickerCalendar)
            If i_calendar IsNot Nothing Then
                If args.ToggleState = Telerik.WinControls.Enumerations.ToggleState.On Then

                    i_calendar.ShowTimePicker = True
                    i_calendar.DropDownMinSize = New Size(450, 350)
                    i_calendar.DropDownMaxSize = New Size(450, 350)
                    .DateTimePickerElement.CalendarSize = New Size(450, 350)
                    .CustomFormat = "dd.MM.yyyy HH:mm" 
                Else
                    i_calendar.ShowTimePicker = False

                    i_calendar.DropDownMinSize = New Size(250, 250)
                    i_calendar.DropDownMaxSize = New Size(250, 250)
                    .DateTimePickerElement.CalendarSize = New Size(250, 250)
                    .CustomFormat = "dd.MM.yyyy"
                End If

Hello,

The CustomColorsConfigLocationNeeded event fires on dialog close but does not seem to fire on dialog open or load. So I can save a custom location for the custom colors when the dialog is closed but can't reference that location when the dialog is subsequently opened again. What am I missing?

Best regards,

Robert

02.{
03.    if (!IsFormOpen(typeof(frmSupplierList)))
04.    {
05.        CloseChildForm();
06.        frmSupplierList m_frmListSupplier = new frmSupplierList
07.        {
08.            Width = this.Width,
09.            Height = this.Height,
10.            MdiParent = this,
11.            MaximizeBox = false,
12.            MinimizeBox = false,
13.            ControlBox = false,
14.            WindowState = FormWindowState.Maximized
15.        };

Please refer to the attached sample project and follow the steps from the gif file. 

You will notice that each time a random group displays only images (no text) when the groups don't fit in the ribbon's width.

Workaround:

        public MDIForm()
        {
            InitializeComponent();
            this.radRibbonBar1.RibbonBarElement.ItemVisiblityStateChanging += this.RibbonBarElement_ItemVisiblityStateChanging;
        }

        private void RibbonBarElement_ItemVisiblityStateChanging(object sender, ItemVisiblityStateChangingEventArgs args)
        {
            if (args.NextVisibilityState == ChunkVisibilityState.NoText)
            {
                args.Cancel = true;
            }

Hi,

Following to the workaroud (flag IsSearchAsync) provided (https://feedback.telerik.com/Project/154/Feedback/Details/245938-fix-radgridview-having-groups-filters-sort-descriptors-and-search-query-in-t), we discovered two issues :

1) the behavior of the grid is changed while using IsSearchAsync as true or false (see 2018-08-01_1849_DragDrop_behavior_with_IsSearchAsync.swf video attached). When set to true, the line found by the searchbox is automatically reselected. When the flag is set to false, it's not the case.

2) while playing with drag&drop, after some time the grid became unstable (see 2018-08-01_1847_-_dragdrop_issue_with_IsAsyncSearch.swf video attached). You can see that at the beginning, the D&D works fine. At 0:20 I can't select any line, and when I try to D&D, it drops always the same customer. At 0:40 you can see that even the SearchBox is broken and the progressbar is looping forever

To reproduce the problem, we need 2 Monitors with different scaling.
Let's say that Monitor 1 has 150% Scaling and Monitor 2 has 100% (Monitor 2 is the main monitor). When starting the program and click on radbutton1, then an empty form (Toolbox) is shown. Move the Toolbox form to the other monitor and then open the RadDropDownList. The problem is that the drop-down is shown not under the control.

Please refer to the attached project.

When deleting all content (e.g. Select All [CTRL+A] + Delete [Del]) in the document, it would be convenient for the user to preserve all formatting (local span formatting + local paragraph formatting + style) applied on the last paragraph. 

This will ensure that the user will continue edit the document with last current font, font family, etc.

If this operation is applied on an empty document, though, the styling of the single paragraph should be reset to the defaults for the document.

Hello,

I'm contacting to you regarding the RadDiagram in WinForms. Currently I have an issue with the layout by using the AStartRouter (see attached picture). Please find below the code used to setup the router:

this.diagram.RoutingService.Router = new Telerik.Windows.Diagrams.Core.AStarRouter(this.diagram.DiagramElement) 

AvoidShapes = true,
WallOptimization = true
};
this.diagram.RoutingService.AutoUpdate = true;
this.diagram.RouteConnections = true;

Thanks for your help.

Hello,

I use radbreadcrumb as a group path explorer in my software. 

I associate it with a treeview. Please see the attache photos.

When I select a treeviewitem which has too much parent levels, the radbreadcrumb can not display the path completely.

I've tried autoscrollmargin and autoscrollminsize. No luck. Because my radbreadcrumb is in a splitcontainerpanel, the display size is changeable.

I expect a custom function can act like Windows Explorer (see the last attach photo). When there is no enough display space, only the last levels are shown.

 

PS. I've integrated the telerik solution from this post. And it works great.

Thank you by advance.
