DataGridViewHeaderCell.MouseEnterUnsharesRow Method

Indicates whether a row will be unshared when the mouse pointer moves over a cell in the row.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected override bool MouseEnterUnsharesRow(
	int rowIndex


Type: System.Int32
The index of the row that the mouse pointer entered.

Return Value

Type: System.Boolean
true if visual styles are enabled, and the DataGridView.EnableHeadersVisualStyles property is true; otherwise, false.

For information about enabling visual styles, see the Application.EnableVisualStyles method.

MouseEnterUnsharesRow is called just before OnMouseEnter. It must return true if the call to OnMouseEnter has the effect of unsharing the row rowIndex. It should return false otherwise.

For more information about row sharing, see Best Practices for Scaling the Windows Forms DataGridView Control.

Notes to Inheritors

When overriding MouseEnterUnsharesRow in a derived class, be sure to call the base class’s MouseEnterUnsharesRow method so that registered delegates receive the event.
