You can make your own version of the shipped VF_UM040O, F_UM044O and VF_UM041O instance list browser.
You might like to do that for two reasons:
- The time taken and resources consumed to create a visible instance list is most influenced by the number of items (rows) you have and the number of visible columns in each item. The generic nature of shipped browsers VF_UM040O and VF_UM041O make them the easiest solution to use. However it also means that they may be slower than a custom instance list browser that you create.
- You might want to visualize your instance list in a way that neither VF_UM040O nor VF_UM041O support.
To understand how to create your own instance list browser examine the shipped sample application Snap In Instance List.
The filter is DF_T41F1O. The snap-in instance list (circled in red) is DF_T41I1O.
Note: If you create your own instance list browser or browser panel, you may need to also produce your own version of built-in-browsers features such as column visibility toggling, column reordering, item sorting, list searching, conversion to CSV data, etc. Whether you do need to do this depends on whether that feature is relevant to the way that your instance list data is visualized. In addition, future enhancements to the built-in browsers may not be automatically available in your custom version.
