Hi Jason,
Thanks for contacting Syncfusion support,
Query 1: If Blanks is used just send something to remove the Blanks
We have analyzed your query and we are not able to reproduce the reported issue. Since it filters correctly and removed the blank value in grid. We have prepared a sample that can be downloaded from the below link.
Also we have attached video link for both the reported issue.
Query 2: If the Search Box is used and Select All is left, then send it over as a "Contains" and the Value rather than the entire list
Based on this query when searching the data in the search box it returns contains value. But along with that it shows the blank value also to filter.
So before proceeding please provide us the following details,
1. Is that you are mentioning the blank value also comes along with it when searching in search box for the particular value?
2. Share the grid code that you have used.
3. Share the video/ screenshot of the issue and the scenario.
4. If possible please reproduce the issue in the above attached sample.
5. Share the JSON data that you have used.
The provided information will help us to analyze the issue and provide you the response as early as possible.
Please let us know if you need further assistance.
Regards,
Manisankar Durai.
