UI for Winforms

In WPF this is possible with custom provider: https://www.telerik.com/forums/map-control-and-web-map-service

How to reproduce:

public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
public RadForm1()
{
InitializeComponent();

this.radGridView1.DataSource = this.GetData();
this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;

GridViewDecimalColumn decimalColumn = this.radGridView1.Columns[0] as GridViewDecimalColumn;
decimalColumn.DecimalPlaces = 2;
decimalColumn.FormatString = "{0:N2}";
decimalColumn.ExcelExportType = DisplayFormatType.Custom;
decimalColumn.ExcelExportFormatString = "0.000";
}

public object GridViewSpreaExport { get; private set; }

private object GetData()
{
DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(double));
dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Bool", typeof(bool));
dt.Columns.Add("Date", typeof(DateTime));

for (int i = 0; i < 100; i++)
{
dt.Rows.Add(1.10 + i, "Name " + i, i % 2 == 0, DateTime.Now.AddDays(i));
}

return dt;
}

private void radButton1_Click(object sender, EventArgs e)
{
GridViewSpreadStreamExport spreadExporter = new GridViewSpreadStreamExport(this.radGridView1);
spreadExporter.FileExportMode = FileExportMode.CreateOrOverrideFile;
SpreadStreamExportRenderer renderer1 = new SpreadStreamExportRenderer();
spreadExporter.RunExportAsync(@"..\..\exported-stream.xlsx", renderer1);

}
}

Workaround: Create a custom SpreadStreamExportRenderer

public class CustomSpreadStreamExportRenderer : SpreadStreamExportRenderer
{
public override void SetCellValue(DataType dataType, object value)
{
switch (dataType)
{
case DataType.Number:
this.SetNumberValue(value);
break;
case DataType.DateTime:
this.SetDateTimeValue(value);
break;
case DataType.Boolean:
this.SetBooleanValue(value);
break;
case DataType.Other:
if (this.SetNumberValue(value))
{
break;
}
if (this.SetDateTimeValue(value))
{
break;
}
if (this.SetBooleanValue(value))
{
break;
}

this.SetStringValue(value);
break;
case DataType.String:
default:
this.SetStringValue(value);
break;
}
}
}

This should work similar to RadGridView. Once should be able to manually set the height of on individual rows as well.

To reproduce: add some nodes to the tree view at design time

public RadForm1()
{
InitializeComponent();

this.radTreeView1.AllowDragDrop = true;
this.radTreeView1.DragEnding += radTreeView1_DragEnding;
}

private void radTreeView1_DragEnding(object sender, Telerik.WinControls.UI.RadTreeViewDragCancelEventArgs e)
{
if (MessageBox.Show("Are you sure you want to move?", "Question", MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.No)
{
e.Cancel = true;
}
}

Then try to drag and drop a node. You will notice that the application hangs

Workaround: use RadMessageBox
