Selection after deleting from binding list

Hi,

Version: 2017.3.1017.20

Code to reproduce problem below. Just create new form and copy-paste code below.

public partial class Form : System.Windows.Forms.Form

{

public Form()

{

InitializeComponent();

}

private void Form_Load(object sender, EventArgs e)

{

RadGridView grid = new RadGridView();

grid.Dock = DockStyle.Left;

grid.SortDescriptors.Add("Id", ListSortDirection.Ascending);

grid.SelectionMode = GridViewSelectionMode.FullRowSelect;

BindingList <X> bindingList = new BindingList<X>();

bindingList.Add(new X() { Id = 1, Name = "Row 1" });

bindingList.Add(new X() { Id = 5, Name = "Row 5" });

bindingList.Add(new X() { Id = 3, Name = "Row 3" });

bindingList.Add(new X() { Id = 4, Name = "Row 4" });

bindingList.Add(new X() { Id = 2, Name = "Row 2" });

bindingList.Add(new X() { Id = 6, Name = "Row 6" });

bindingList.Add(new X() { Id = 7, Name = "Row 7" });

bindingList.Add(new X() { Id = 8, Name = "Row 8" });

bindingList.Add(new X() { Id = 9, Name = "Row 9" });

bindingList.Add(new X() { Id = 10, Name = "Row 10" });

Controls.Add(grid);

grid.DataSource = bindingList;

RadButton radButton = new RadButton();

radButton.Text = "Delete row";

radButton.Dock = DockStyle.Right;

radButton.Click += delegate

{

var selected = (X)grid.CurrentRow.DataBoundItem;

bindingList.Remove(selected);

};

Controls.Add(radButton);

}

public class X

{

public Int32 Id { get; set; }

public String Name { get; set; }

}

My grid is connected to binding list. Clicking on the button remove currently selected row from binding list.

The problem is: Sometimes after deleting, nearest row is selected. Sometimes grid is clearing selection.

Please see attached gif.

I would like the next record to be always selected after deleting current one.

If deleted row was last row, it should select previous one.

I was trying to use GridNavigator.SelectPreviousRow(1) and GridNavigator.SelectNextRow(1) but it do not work, becouse sometimes after deleting row grid is clearing selection.

Set Day of Week in Recurrence Dialog

How can I set it up so that when a user selects a day in the Scheduler, then selects to create a recurring appointment, the Edit Recurring Appointment dialog will, when Weekly recurrence type is selected, set the Day of Week to the Day of Week selected in the calendar, NOT the Day of Week in real-time.

Thank you!

Different interval for each child control of the rotator

Hello there,

I have a rotator which rotates different web browser controls. I would like to play a video inside some of the browsers using the HTML5 <video> tag. The problem is that I need to rotate to the next control only when the video has finished playing. Is it possible to set different intervals for each of the rotator's children? If not then is there an event I can handle which occurs when the rotator starts rotating it's content?

Kind Regards.
