winforms - DataGridView is not painted properly -


i have datagridview in wizard created using tabcontrol. when datagridview shown, mixture of cell contents , previous wizard page displayed. when click next show next wizard page , go previous page, datagridview display correctly. take picture of this:

enter image description here

first cell right in first row corrupted. how can fix this?

edit: can reproduce bug way: place small dgv in form. dgv width 268 , height 247. add 6 columns it. put these lines of code in form load event method:

string[] row = new string[6]; (int = 0; < 10; i++) {     row[0] = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";     row[1] = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";     row[2] = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";     row[3] = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";     row[4] = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";     row[5] = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";     datagridview1.rows.add(row); }

finally go dgv properties defaultcellstyle , change backcolor transparent. run , thing need scroll right. picture of problem:
