Hey @Simple_Works ,

If your original condition (String.IsNullOrEmpty(Row("Status").ToString)) is not working as expected, here are a few alternative solutions you can try:

Solution 1: Use IsDBNull Check

Sometimes, data from a database can have DBNull values. To handle that, you can combine IsDBNull with String.IsNullOrWhiteSpace:

If IsDBNull(Row("Status")) OrElse String.IsNullOrWhiteSpace(Row("Status").ToString)

Solution 2: Use String.IsNullOrWhiteSpace Instead

If the issue is due to whitespace characters (like spaces or tabs), try this:

If String.IsNullOrWhiteSpace(Row("Status").ToString)

This checks for null, empty strings, and strings that only contain whitespace.

Solution 3: Check for Nothing

If your row might be Nothing, add a check for that:

If Row("Status") Is Nothing OrElse String.IsNullOrEmpty(Row("Status").ToString)

Solution 4: Use Trim to Remove Extra Spaces

Sometimes, there could be leading or trailing spaces. Use Trim() to clean up the value:

If String.IsNullOrEmpty(Row("Status").ToString.Trim)

Solution 5: Combine All Checks for Robustness

For a more comprehensive check:

If IsDBNull(Row("Status")) OrElse Row("Status") Is Nothing OrElse String.IsNullOrWhiteSpace(Row("Status").ToString.Trim)

Explanation:

  • IsDBNull handles cases where the database column has DBNull values.
  • String.IsNullOrWhiteSpace covers null, empty strings, and strings with only spaces.
  • Trim() removes any extra spaces that may cause unexpected behavior.

Try these solutions and see which one works for your specific scenario. Let me know if you need more help! :blush:

Best,
