Filtering of gallery based on the drop-down value

Gallery filter function based on the drop-down value


Problem statement

If we use the data source directly to the gallery, we may face the delegation issues. To avoid that we can use a drop-down to filter a gallery.


Resolution

  • We can add a drop-down and map a related entity to filter a gallery.
  • For this i have added a drop-down control and mapped a course entity for it.
  • To insert a drop-down control – go to the insert menu in the ribbon bar, and select input following by select the drop-down control or combo box control.
  • After adding it to the screen, select the items property of the control and select the entity you want to use.

Write a Code as mention in the image.
