c# - weird Logic error in dataGridView table in C #

Question

I displayed my database tables into dataGridViews, by binding it (from the tiny arrow in top right corner) directly, after that Visual Studio add this line this.gseTableAdapter.Fill(this.labxDataSet.gse); the problem is when i try to open the table form (form who displayed this dataGridView) all my project throw's this error my error the second line and third line work will, Now i tried to solved this issue by delete this line and display table data from database into dataGridView by using code

                
                OleDbDataAdapter da;
                da1 = new OleDbDataAdapter("SELECT * FROM gse", con0);
                DataTable dt1 = new DataTable();
                da1.Fill(dt1);
                dataGridView1.DataSource = dt1;

this finale code works perfect. why the first line doesn't work?
