Safihur. Where are you updating? .. are you trying to update database or DataTable...Because, the update query doesn't do anything...

Solution 1

C#

SqlCommand cmd = new SqlCommand("Update tableupd set AssignedPriority=@AssignedPriority where JobCode=@JobCode");

You have only declared a SqlCommand object. Do the following...

You need to assign its Connection Property to your Database ConnectionString.
Then define the parameters you have used in the Command Query that are "@AssignedPriority" and "@JobCode".
Open the SqlConnection.
At last, Execute the Command using SqlCommand.ExecuteNonQuery Method[^].

Then update the Table. Why are you are creating a Command?
