Gets or sets the tab order of the control within its container.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
A tab index can consist of any valid integer greater than or equal to zero, lower numbers being earlier in the tab order. If more than one control on the same parent control has the same tab index, the z-order of the controls determines the order to cycle through the controls.
For a control to be included in the tab order, its TabStop property must be set to true.
The following code example adds a Button to a form and sets some of its common properties. The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. Next it sets the BackgroundImage and resizes the button to the same size as the Image. The example then sets the TabStop to true and sets the property. Lastly, it adds an event handler to handle the Click event of the button. This example requires that you have an ImageList named imageList1.
