Get data from DataGridView

Question

Hello everyone.I have a problem with reading data from DataGridView to array. Use code: int[] n = new int[319]; for (int i = 1; i <= StartDataView.Rows.Count; i++) { for (int j = 1; j <= StartDataView.Columns.Count; j++) { n[i - 1 j - 1] = (int)StartDataView.Rows[i].Cells[j].Value; } } but all values results is nullI tried Value.ToString()but also no result.What I do wrong?

Hi try below code and make sure your datagridview contains integer values only. n[i - 1 j - 1] = int.Parse(StartDataView.Rows[i].Cells[j].Value.ToString()); it may help you.

for your sample data... try this code... int[] n = new int[319]; for (int i = 0; i { for (int j = 0; j { try { n[i j] = int.Parse(this.StartDataView.Rows[i].Cells[j].Value.ToString()); } catch(Exception Ee) { //get exception of null MessageBox.Show(Ee.ToString()); } } } if any exception occur inform me.

i have some questions 1.how many rows & columns are available in your datagridview?. is it 3 rows and 19 columns?.. 2.can you show me some sample content of your cells.?whether all are integer values?.is there any cell with empty strings()?. 3.whether you want to retrieve all the rows values or particular rows?.because your for loop starts with 1.so it will read from 2nd rows 2nd columns.
