Visual Studio-表单未使用sql数据库更新

Question

I have an issue where I have created a form, added a table through a DataSource to an SQL database. Everything has worked fine.

I have now needed to change a column from varchar(8) to varchar(255) which has been done and is fine. My issue is that upon opening my form I have a red ! on my columns saying ;

Column 'UserId' exceeds the MaxLength limit.

It lets me add through the form to the database with no issue. But always populates this issue on form opening.

Please may somebody point me in the right direction to get the form to update along with the SQL Database?

I assume it is the Adaptor but I very well may be wrong. I am new to VS and I have not been able to find the correct answer so far so I am hoping for some advice.

Thanks!

您需要重新创建DataSource对象-它具有仍然具有旧长度限制的验证规则。
