BeforeRowResize Event

Occurs before a row has been resized.

Syntax

Visual Basic

'Declaration
 
Public Event BeforeRowResize As BeforeRowResizeEventHandler

C#

public event BeforeRowResizeEventHandler BeforeRowResize

Event Data

The event handler receives an argument of type BeforeRowResizeEventArgs containing data related to this event. The following BeforeRowResizeEventArgs properties provide information specific to this event.

Property	Description
Cancel (Inherited from System.ComponentModel.CancelEventArgs)
NewHeight	The new height (read-only)
Row	The row (read-only)

Remarks

The row argument returns a reference to an UltraGridRow object that can be used to set properties of, and invoke methods on, the row that will be resized. You can use this reference to access any of the returned row's properties or methods.

The rowheight argument indicates the new height of the row. The current height is indicated by the Height property of the UltraGridRow object returned by row.

The cancel argument enables you to programmatically prevent the row from being resized. This argument can be used to prevent the row from resizing unless a certain condition is met.

Depending on the value of the RowSizing property, more than one row can be affected by the resize. In this case, row refers to the original row being resized.

The AfterRowResize event, which occurs after a row has been resized, is generated after this event, provided cancel is not set to True.

Example

Following code shows how you can use BeforeRowResize event to prevent the user from resizing a row to heights greater than 50 pixels.
