RadSpreadsheet: Resizing is very slow and doesn't produce correct layout

Add a RadSpreadsheet on the form and try resizing it at design time. You will notice that the control is resized after a considerable delay.

If you Dock the control to Fill and try resizing the form at run you will notice that the layout is incorrect. The attached gif file illustrates the obtained behavior.

Workaround: update the layout after resizing:

        public RadForm1()
        {
            InitializeComponent();
            this.radSpreadsheet1.SizeChanged+=radSpreadsheet1_SizeChanged;
        }

        private void radSpreadsheet1_SizeChanged(object sender, EventArgs e)
        {
            this.radSpreadsheet1.SpreadsheetElement.InvalidateMeasure(true);
            this.radSpreadsheet1.SpreadsheetElement.UpdateLayout();
        }

Dear Dess,

 

Thanks. I do have two other issues and one is more serious(it throws Keys not found exception with UI interactions). We're seeking now for reproduction condition. It is a separate issue so I'll open a new ticket within a few days

Thanks. It solves the problem. Still, I believe the users will almost always need this feature and should be asked to opt out from this, instead of opt in.

Thank you again for your fast reply.
