Problem with OleDBConnection and WindowForm

Hello,

this is my first post here, so dont get me wrong :p I have 2 diffrents problems with OleDBConnection. First problem is that when i open for example. access database my window from get smaller and elements are bugged. 

Second problem is that when i change value in a cell in my datagridrow, source dataset get this change too but problem is when i fire method HasChanged() on my dataset it gives me false so its like i didnt modified cells. But when i remove or add row its get changes so idk what im doing wrong. Here is code how i change my datagridview values on cells:

            okienko.dataGridView1.Rows[index_wiersza].Cells[1].Value = textBox2.Text;
