Creating a custom toolbar option

With the form open in Design Mode, add a component of type Toolbar Button to the form.
In the Component Properties grid, set the component properties as desired.

At the least, you should set the Name , Caption , and Bitmap File Name properties. Your graphics file should be 15x15 pixels, in .JPG or .PNG format.
Save the form definition.

Now, when you set the DisplayMobileToolbar form variable to True, your custom toolbar button appears just to the right of any standard operation buttons you have chosen to display on the toolbar.

Note: When you create a custom toolbar button, the system is set to automatically display the button whenever the DisplayMobileToolbar form variable is set to True. Unlike the standard operations, there is no need to set a Standard Operations property to True.
