DrawListViewSubItemEventArgs.DrawFocusRectangle(Rectangle) Method

Definition

Draws a focus rectangle for the ListViewItem.ListViewSubItem if the parent ListViewItem has focus.

public:
 void DrawFocusRectangle(System::Drawing::Rectangle bounds);
public void DrawFocusRectangle (System.Drawing.Rectangle bounds);
member this.DrawFocusRectangle : System.Drawing.Rectangle -> unit
Public Sub DrawFocusRectangle (bounds As Rectangle)

Parameters

bounds
Rectangle

The area within which to draw the focus rectangle.

Remarks

Use this method to draw a standard focus rectangle around the subitem. The focus rectangle is drawn one pixel inside the area specified by the bounds parameter. It is drawn only when the parent item has focus, so you do not need to check the focus state of the item before you call this method.

You might want to draw the focus rectangle only around the first subitem (that is, the parent item, which is displayed in the first column) rather than drawing it around every subitem of an item. This corresponds to the normal behavior of a ListView control when the ListView.FullRowSelect property is set to false. To draw the focus rectangle around the first subitem, call the DrawFocusRectangle method only when the ColumnIndex value is 0.

The ListView control does not provide the ability to select individual subitems, but if you want to implement subitem selection yourself, you can use this method to draw the focus rectangle around a subitem other than the first one.
