Syntax

[C1Description("Fires before the current cell changes (Row and Col properties).")]
public event RangeEventHandler BeforeRowColChange

[C1Description("Fires before the current cell changes (Row and Col properties).")]
public:
event RangeEventHandler^ BeforeRowColChange

'Declaration
 
<C1DescriptionAttribute("Fires before the current cell changes (Row and Col properties).")>
Public Event BeforeRowColChange As RangeEventHandler

'Usage
 
Dim instance As C1FlexGridBase
Dim handler As RangeEventHandler
 
AddHandler instance.BeforeRowColChange, handler

This event fires before the Row or Col properties change, either as a result of user actions or through code. It allows you to prevent the selection of certain cells, thus creating "protected" ranges on a grid.

BeforeRowColChange fires only when the Row or Col properties are about to change. To detect extended selections, you also need to handle the BeforeSelChange event.
