I have updated my OS to Win 10 from Win 8.1 and now none of the RadForms will open in VS 2015 Designer. Some esoteric error message: "Value cannot be null. Parameter name: instance" is displayed. Is there something I could do other than re-installing the entire Telerik product line?

Use LogarithmicAxis and set the Minimum to 0.1

Workaround is availble in the atched project.

To reproduce: please refer to the attached sample project. Note that the CellValidating event is fired twice even without showing a RadMessageBox. With an MS Button the problem is not reproducible.

Workaround: use the RadGridView.ValueChanging event to perform validation while the user is typing in the active editor:
 private void radGridView1_ValueChanging(object sender, Telerik.WinControls.UI.ValueChangingEventArgs e)
 {
   if (((string)e.NewValue) != "x")
     {
         RadMessageBox.Show("Only 'x' allowed!");
         e.Cancel = true;
     }
 }

Request is to have the ability preferably using a mouse drag to change the height of the column headers in the grid. We can already do that for data rows of the grid, but it is not possible currently to do the same for the header row.

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.

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

Workaround: when you set the DrawFill property to true, specify the BackColor to the desired one and reset for the rest of the cells.

private void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    if (e.Column.Name == "ProductName" && e.Row is GridViewDataRowInfo)
    {
        if (e.CellElement.Value.ToString().Contains("C"))
        {
            e.CellElement.DrawFill = true;
            e.CellElement.BackColor = Color.Yellow;
            e.CellElement.GradientStyle = GradientStyles.Solid;
            e.CellElement.ForeColor = Color.OliveDrab;
        }
        else
        { 
            e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
            e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
            e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);  
            e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);  
        }
    }
    else
    { 
        e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);    
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);  
    }
}

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

Workaround: in order to cancel adding of the new row, you can call the MasterView.TableAddNewRow.CancelAddNewRow method:

private void radGridView1_UserAddingRow(object sender, Telerik.WinControls.UI.GridViewRowCancelEventArgs e)
{
    e.Cancel = true;
    this.radGridView1.MasterView.TableAddNewRow.CancelAddNewRow(); 
    int index = this.radGridView1.Rows.Count;
    this.radGridView1.Rows.Add(index, "Row" + index);
}

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
