GridViewDecimalColumn - up/down arrow keys move between rows

I have a RadGridView with a GridViewDecimalColumn. I want to allow the user to move up and down to other rows using the up/down arrow keys, but it changes the value instead. This occurs even if I set ShowUpDownButtons to false.

I found an old example on the forum that explains how to change this behavior here: https://www.telerik.com/forums/gridviewdecimalcolumn-up-down-key. However when I try the code there, I can't get it to work. GridSpinEditorElement is not found. I have the Telerik.WinControls and Telerik.WinControls.UI namespaces included.

I looked up GridSpinEditorElement, to see if I needed a different namespace, and it seems it's no longer available. I'm referencing this page:

https://docs.telerik.com/devtools/winforms/api/html/t_telerik_wincontrols_ui_gridspineditorelement.htm

It says it's obsolete and shows version 2018.1.220.40. I'm on version 2018.3.911.40.

How can I implement this code now without GridSpinEditorElement?

Thanks

GetStatisticsInfo throws NullReferenceException on newly created document

I need to determine if document is empty, even if the document was just created in other parts of the code. The code below throws the exception. If the commented lines are uncommented then the exception is not thrown. I could work around the problem also by carrying a flag to tell me if document was just created (and not call GetStatisticsInfo in that case). Is this exception a bug? Is there a smarter or more elegant way to determine if document is empty?

var d = new RadDocument();

//var p = new Telerik.WinForms.Documents.FormatProviders.Rtf.RtfFormatProvider();

//d = p.Import(p.Export(d));

var s = d.GetStatisticsInfo();

Adding new row

Hi,

I am binding data from a datatable to the VirtualGrid but currently there is no data in it, so I would like to have a blank row appear in the grid which will allow the user to enter new rows.

Currently if there are no data then nothing is showing in the grid, only when some data is there "Click here to add a new row" appears.

AllowAddNewRow is true.

Combox : How Assign Value to Predefined Combox Column

Hi everyone

While I am learning Telerik Radgridview control, I am stuck with combo box column example. I have created the grid and columns using GUI property builder. It's not bound to any database. I just want to display a simple drop-down list. For example:- {Yes, No, Maybe}

My Question
1. How to assign the drop-down list Item? {Yes, No, Maybe}
2. Is it possible to assign different values to each combo box cell per row
For Example:-

row(0)= {Yes, No, Maybe},

row(1)={Absoluitely, Definately, Certain}
Technical Info
Gridview Name: radGridView1
Combobox Column Name: status
Application Type: VB.net WinForm

I think its a very basic question, but somehow I am unable to find the solution. It will be very kind if someone guide me to the solution.
