Hi all,

I'm stuck with this problem:

I am loading data from my stock table into a datagridview
and also then saves the data into antoher table(Sales Table).

Thats working good, but where my problem comes in is, I also have a remove button on my Datagridview that is supose to remove the data. It remove it from the datagridview nicely, but from my sales table to remove it there is the problem.

I was thinking on maybe when it save to the sales table it must
send back the Pk_ID of that table.

But How??

Please any help or ideas would be appriciated!!!

You probably bind the gridview with a datatable.

When you are binding it to Datagridview, you can check DataTable.IsPrimaryKey property to identity which one column is primary key and when delete record you can use that primary key.

Here is the link for how to use:

Solution 2

You need to use a query like
Delete from sales where SalesId = value
SalesId would be your primary key.
