Problem with loops

Question

Hi I have a different numbers in a datagridview. Now my problem here is: I want to write code into button click event. Once button is clicked i should show message boxes. The no of message boxes depends on the numbers in datagrid view. for example i have 50 numbers in datagridview i should show 5 message boxes with each 10 numbers. if i have 60 numbers in a datagridvies i should show 6 message boxes with each 10 numbers. Everything should happen in one button click. Please give me ideas to do. Darma

OK in that case try this: private void button1_Click(object sender EventArgs e) { string[] array = new string[10]; int count = 0; for (int i = 0; i { DataGridViewRow row = dataGridView1.Rows[i]; if (!row.IsNewRow) { array[count] = row.Cells[0].Value.ToString(); count++; } if (count == 10 || i == dataGridView1.Rows.Count - 1) { MessageBox.Show(String.Join(  array)); Array.Clear(array 0 10); count = 0; } } }

Hi Vulpes Thanks allot for ur reply. Actually one row has one number. It means 50 numbers means 50 rows. 60 numbers has 60 rows in gridview. Darma

You haven't said where the numbers are in the datagridview. This code assumes they're arranged in rows of 10 so there are 5 rows for 50 numbers and 6 rows for 60 numbers. It also assumes that none of the cells are null. Notice also that you can't show more than one MessageBox at a time - you have to wait until the previous one is closed before you can display the next one: private void button1_Click(object sender EventArgs e) { string[] array = new string[10]; foreach (DataGridViewRow row in dataGridView1.Rows) { if (row.IsNewRow) return; for (int i = 0; i { array[i] = row.Cells[i].Value.ToString(); } MessageBox.Show(String.Join(  array)); } }
