The user resizes the columns.
|VB.NET||Private Sub object_ColumnSize(ByVal sender As Object, ByVal e As EventArgumentType) Handles object.ColumnSize|
|VB||Private Sub object_ColumnSize()|
|C#.NET||void object_ColumnSize(object sender, EventArgumentType e);|
When a user is about to resize a column, the ColumnSizeStarted event occurs (as the user presses the left mouse button in the column resizing area, before the column width changes). As the column is resized, the ColumnSize event can occur multiple times. Once the user releases the mouse button used to resize the column, the ColumnSizeEnded event occurs. These events also occur identically during splitter bar resizing.
The ColumnSize event allows the application to adjust the column sizes if necessary, after the user resizes the columns.
