Hello telerik
I have a gridview and add it a column like this

GridViewDecimalColumn dec = new GridViewDecimalColumn();
            dec.FieldName = "Flaot";
            dec.Name = "Float";
            dec.HeaderText = "Float";
            dec.DataType = typeof(decimal);
            dec.FormatString = "{0:#,0.########}";
            dec.ShowUpDownButtons = false;
            dec.DecimalPlaces = 8;
            radGridView1.Columns.Add(dec);
I didint want to see UpDownButton so I set  ShowUpDownButtons  =false , in edit mode The ShowUpDownButtons doesnt shown but when I use Up or Down button
it increase and Decrease the value of cell.Is there any way to stop this behavior.(I am using the version 2014-1-226)

Hello Mahtab,

Thank you for writing.

You would need to add the following setting to your GridViewDecimalColumn:
GridViewDecimalColumn dec = new GridViewDecimalColumn();
dec.Step = 0;

With the step being 0 you would not be able to change the value of the cell with the up and down keys as well as with the mouse scroll wheel.

I hope this helps. Should you have further questions please do not hesitate to write back.

Thank you Hristo for the reply It was helpful but I need another thing ,when I use Up key I want to go to the next row and when I use Down Key I want t go to previous row so I write the code bellow
 private void GrdItm_CellEditorInitialized(object sender, GridViewCellEventArgs e)
 {
if (GrdItm.CurrentColumn is GridViewDecimalColumn)
            {
                GridSpinEditor editor = e.ActiveEditor as GridSpinEditor;
                if (editor != null)
                {
                    GridSpinEditorElement el = editor.EditorElement as GridSpinEditorElement;
                    if (el.TextBoxItem.TextBoxControl.Text.Contains('.'))
                    {
                        el.TextBoxItem.TextBoxControl.Text = el.TextBoxItem.TextBoxControl.Text.TrimEnd('0');
                        el.TextBoxItem.TextBoxControl.Text = el.TextBoxItem.TextBoxControl.Text.TrimEnd('.');
                    }
                    el.InterceptArrowKeys = false;
                    el.TextBoxItem.KeyDown -= new KeyEventHandler(GrdItm_GridSpinEditorTextBox_KeyDown);
                    el.TextBoxItem.KeyDown += new KeyEventHandler(GrdItm_GridSpinEditorTextBox_KeyDown);

                }
            }
}

 void GrdItm_GridSpinEditorTextBox_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Up)
            {
                GrdItm.GridNavigator.SelectPreviousRow(1);
            }
            else if (e.KeyCode == Keys.Down)
            {
                GrdItm.GridNavigator.SelectNextRow(1);
            }
        }


But I want to Know is there any other way to achieve it
