Hi,

I want to get the values from a for loop separated with comma in to a single message box.
Below is my for loop.

C#

for (int i = 0; i < dtgrdUnconfirm.Rows.Count; i++)
                {
                    DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
                    ch1 = (DataGridViewCheckBoxCell)dtgrdUnconfirm.Rows[i].Cells[0];
                    if (ch1.Value != null &&
                           Convert.ToBoolean(ch1.Value) == true)
                    {
                        data = (dtgrdUnconfirm.Rows[i].Cells[6].Value.ToString());
                    }
                }

In this for loop, string data will get 4 values and I want those 4 values to be shown in a single message box separated with comma. For example, output should be 1,2,3,4

Thanks in advance

You can concatenate string using data += string.Format("{0},", dtgrdUnconfirm.Rows[i].Cells[6].Value.ToString()); and finally trim the last comma.
You should use StringBuilder.

Hi,
I just modified your code

C#

for (int i = 0; i < dtgrdUnconfirm.Rows.Count; i++)
                {
                    DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
                    ch1 = (DataGridViewCheckBoxCell)dtgrdUnconfirm.Rows[i].Cells[0];
                    if (ch1.Value != null &&
                           Convert.ToBoolean(ch1.Value) == true)
                    {
                        data += (dtgrdUnconfirm.Rows[i].Cells[6].Value.ToString())+",";
                    }
                }
             MessageBox.Show(data);
