Hi,
How can we filter the available options of a DropDownList based on the value of another cell same row where both values are loaded from database.

Example:
Cell1, value A Cell2 Options A1, A2
Cell1 value B Cell2 Options B1, B2
Cell1 value A Cell2 Options A1, A2
Cell value C Cell2 Options C1,C2,C3
Thanks!

Try to set the visibility of the drop-down list items depending on the value in the master cell in the RequestEdit event. This event is raised before the user starts editing, i.e. when the drop-down list is opened. You can enumerate the items of the drop-down list and set their visibility with the iGDropDownListItem.Visible property.
