Gets or sets a value indicating whether a sizing handle (grip) is displayed in the lower-right corner of the control.
Documentation for this section has not yet been entered.
You can use the StatusStrip.SizingGrip property to display a grip to provide an indication to the user of when a System.Windows.Forms.StatusStrip is resizable.
Even with the StatusStrip.SizingGrip property set to true and the StatusStrip.GripStyle property set to Visible, the sizing grip will not be displayed unless you also set the ToolStrip.LayoutStyle property to one of the overflow values. If the ToolStrip.LayoutStyle property is set to ToolStripLayoutStyle.Flow or ToolStripLayoutStyle.Table, the sizing grip will not be displayed.
