I am using cascade dropdownlist using OData anf filter options also using parameter map and I am having 3 dropdown.
All binding I did from html page and is working fine from binding side. Now cascade works only in first two dropdown but not with 3rd dropdown.
My unique case is that I am having only one datasource and using same datasource I am applying different filters for 3 dropdowns like first to second and second to third and using some column as from field.
I am not able to get why is working only for first two dropdown and seen that 3rd one is always enabled but when I change value in 2nd , the value is 3rd is populating.
Also while loading the page even if 3rd dropdown is using from field of 2nd then why query is being fired to get the filters and data.
Please help as I discussed in my team but no luck till date, even not able to find in telerik about using one datasource for casacading. FYI --> I tried cascade method from code also but same issue.
