To reproduce: please refer to the attached sample project and gif file.

Workaround: this.radTextBox1.MinimumSize = new System.Drawing.Size(0, 25);
or
Use RadTextBoxControl

Workaround:

    DataTable dt = new DataTable();
    dt.Columns.Add("Id");
    dt.Columns.Add("Name");
    for (int i = 0; i < 5; i++)

    this.radGridView1.ViewDefinition = new CustomTableViewDefition();

1. 2 Monitors configured. The primary display is 16:9 (laptop), the second display has an aspect ratio is 16:10 (desktop monitor).
2. move sample Telerik WinForm app to secondary display (desktop monitor)
3. Click on maximize button

Result: Application width is more then monitor size, as result application is truncated from right.

The same happens with "RadControls for WinForms Q1 2010 Demos" which I have installed on my PC

To reproduce:
- Add 3 MDI child forms with a lot of gauges.
- Set their WindowState to maximized.
- Show each upon a button click.

Workaround:
Set the state of all forms to normal, before adding a new maximized form.

Stop Expanding ALL the Telerik Toolbox control groups when Visual Studio 2017 loads a project! YES, we know your there! We PUT you there.. If we need you, we know where you are! Please quit over-convoluting the toolbox menu by obnoxiously expanding all your toolbox control groups!

To reproduce: the purpose is to have only one label with at a specific value. Hence, you try to adjust the start/end index of the labels and according to the labels count, you get the desired result. A similar approach is applicable for the ticks, but it hides all labels when you try to set a value for the LabelEndVisibleRange .

To reproduce: run the attached sample project. Select an item and press F2, select a new item from the drop-down. You will encounter an error because the ActiveEditor is now null in the ItemValueChanging event.

Workaround: in the EditorInitialized event you can subscribe to the RadDropDownListElement.SelectedIndexChanging event:

private void radListView1_EditorInitialized(object sender, ListViewItemEditorInitializedEventArgs e)
{
    ListViewDropDownListEditor editor = e.Editor as ListViewDropDownListEditor;
    if (editor==null)
    {
        return;
    }
    RadDropDownListElement dropdown = (RadDropDownListElement)editor.EditorElement;
    dropdown.SelectedIndexChanging-=dropdown_SelectedIndexChanging;
    dropdown.SelectedIndexChanging+=dropdown_SelectedIndexChanging;
}

To reproduce:
1. Add a RadCollapsiblePanel and change the back color or border of the container via the Edit UI elements dialog.
2. Save the changes and run the project. You will notice that the style is reset and the changes are not preserved. 

Workaround: Customize the style at runtime. The following help article gives you information about the internal elements structure of the RadCollapsiblePanel: https://docs.telerik.com/devtools/winforms/panels-and-labels/collapsiblepanel/structure

To reproduce: please refer to the attached sample project and try to reorder a node. You will notice that the message box is not rendered properly.

        //case 2
        private void DragDropService_PreviewDragDrop(object sender, RadDropEventArgs e)
        {
             e.Handled = true;
            RadMessageBox.Show(this, "Showing a messagebox under dragending doesn't work correctly.");
        }

        //case 1
        private void radTreeView1_DragEnding(object sender, Telerik.WinControls.UI.RadTreeViewDragCancelEventArgs e)
        {
            //e.Cancel = true;
            //RadMessageBox.Show(this, "Showing a messagebox under dragending doesn't work correctly.");
        }

Workaround: subscribe to the TreeViewElement.DragDropService.PreviewDragDrop and set the Handled argument to true if you want to cancel the drop operation. Then, handle the TreeViewElement.DragDropService.Stopped event and show the desired message.

        public Form1()
        {
            InitializeComponent();
            
            this.radTreeView1.TreeViewElement.DragDropService.PreviewDragDrop += DragDropService_PreviewDragDrop;
            this.radTreeView1.TreeViewElement.DragDropService.Stopped+=DragDropService_Stopped;
        }

        private void DragDropService_Stopped(object sender, EventArgs e)
        {
            
            RadMessageBox.Show(this, "Showing a messagebox under dragending doesn't work correctly.");

To reproduce: please refer to the attached sample project  and gif file illustrating the behavior on my end. 

Note: similar to the axis, the series should also have ClipLabels property which will control whether the labels will be clipped or not.

Workaround: use custom renderer:

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

There should be a Enum (Left, Right, None) property of the Expander Column indicating whether the position of the expander column should be left right or none.  This would be especially important during pinning activities meaning no matter how many columns are being pinned and repositioned in the pinned area of the grid, it would always remain on the left, right or none.
