When change in first row of dropdown then 13 th row dropdown changes automatically #14305

After an investigation, I assume that this behavior is observed because of the virtualization of the igx-grid and because only the first 12 rows are displayed initially.

Result

When change in first row of dropdown then 13 th row dropdown changes automatically

Expected result

When change in first row of dropdown then 13 th row should not show data from first row dropdown

Attached is the sample code

@jackofdiamond5 , since the templates are being reused during the scroll the combos are getting updated inputs instead of being recreated. When the id of a combo in the template changes , it is no longer able to find its selected state from the service and throws an exception. The fix could be as simple as having some reinit logic around an id setter but it needs further investigation.
