Identifier field


Metadata properties set to true


The minimum distance that is defined by DragIncrement is reinitialized continually as the user drags the mouse. For example, when you drag the GridSplitter by the DragIncrement amount, the rows or columns are resized. To resize the rows and columns more, you must drag the GridSplitter the same amount. Therefore, changes to column and row sizes that are made by using the mouse or the keyboard to move the GridSplitter are made in multiples of the DragIncrement.

The following example shows how to set the DragIncrement property.

<GridSplitter DragIncrement="10"  Width="5"
              Grid.Column="0" Grid.RowSpan="2"/>

myGridSplitter.DragIncrement = 10;
