Hello,

in the ControlDefault theme all documentwindows have this cutted edge. In all other themes is it a full rectangle. Is this adjustable?

Thank you for your answer.

Hi

I’m using the RadDock and have a few issues with docking and floating windows.

1. The default size for floating windows is 300 x 300. I know I can set the DefaultFloatingSize but I'd prefer if it stayed the same size as when it was docked. I’ve tried the FloatingWindowCreated event but can’t identify the tab on it as that hasn’t happened yet. Do you think it’s possible?

2. I can float a DocumentWindow or ToolWindow by double clicking the title bar but double clicking it again doesn't make it redock. I could use the MouseDoubleClick event to programmatically set the DockState but how do I check the user clicked the title bar?

3. If I redock a floating DocumentWindow with the ‘Dockable’ context menu option, it doesn't go to its original location. It goes to the first position of the topmost horizontal tab group. It's worse if I have one tab at the top with multiple tabs grouped underneath and float the top tab; it redocks next to the multiple tabs at the bottom and leaves a big empty space where it was located originally (see attached images). Note: the Dockable option works for ToolWindows; if I dock one ToolWindow on the left and another on the right, each redocks to the correct location.

I'm using version 2016.608.40 of RadDock and tried 2017.1.21.40 as well.

I have created a class based off the MaskedEditBox. However, every time I drop it on a form, it auto populates the value with "1____-____". If I drop another on the same form, it populates the value with "2____-____".  Is this done by design?  My desired value would be "_____-____" or "" as the value.

I have a RadMaskedEditBox with the MaskType set to "DateTime", the Mask set to "MM/dd/yyyy", TextMaskFormat set to "includeLiterals". This control is programmatically bound to an object in which the Date/Time value can be null.  in the KeyDown event of the control, if the user presses the "DELETE" key and the selected text is the same as the text value and the selected text length is > 0, I clear the textbox using the "CLEAR()" method and then set the value to null. 

However, the display value now changes to "01/01/0001".

What am I missing. 

Here is my "KeyDown" event

Hello to all!

I'm using C#.

I have a RadListView that I only ever display in ListView mode. I have created a custom SimpleListViewVisualItem descendant, which has a DockLayoutPanel, inside of which is a GridLayout and another DockLayoutPanel, and inside the second DockLayoutPanel is a RadButtonElement, two RadDropDownListElement, and a RadTextBoxElement.

The first two attachments show the issue, both with and without the vertical scrollbar.

I ***believe*** I have all the appropriate ClipDrawing states set, because the RadDropDownListElement is clipping just fine (third attachment).

Is this a known issue?

Thanks.

Sam.

Purples: 

    I have a master-details gridview, but the data should be refreshed when the source data is changed. I implemented INotifyPropertyChanged interface for the model class. However, when I use the hierarchical gridview, when the binding data is changed, the gridview could NOT always work fine.

The attached is my test program.

The first level is Product, the child level is its orders.

I have a background thread to update the product and orders.

I am using 2017.1.221.40.Trial.

CODE below:

----------------------------------------------------------------------

 public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    {
        BindingList<ProductData> _tradeProdDataList = new BindingList<ProductData>();      
        public RadForm1()
        {
            InitializeComponent();
            GenenateData();
            this.radGridView1.DataSource = _tradeProdDataList;
           
            this.radGridView1.AutoGenerateHierarchy = true;
        }
        
        private void GenenateData()
        {
            for (int i = 0; i < 10; i++)
            {
                var prod = new ProductData() { ID = i };
                _tradeProdDataList.Add(prod);
            
                var list = new List<OrderData>();
                for (int j = 0; j < 10; j++)
                {
                    var o = new OrderData() { ProductID = i, OrderName = string.Format("Test-{0}-{1}", i, j) };
                    list.Add(o);
                }
                prod.Orders.AddRange(list);
            }
        }

        private void radButton1_Click(object sender, EventArgs e)
        {
            var t1= Task.Factory.StartNew(new Action(() =>

                while (true)
                {
                    _tradeProdDataList.ToList().ForEach(p =>
                    {
                        p.Quantity = new Random().NextDouble() * 1000.0;
                        p.Orders.ToList().ForEach(o =>
                        {
                            o.LastPx = new Random().NextDouble() * 1000.0;
                        });
                    });
                }

    }

        private double _LastPx;
