Hi All,
Need some feedback, I am trying to copy a column value from datagridview1 to dgv2. If I pressed the button for the first time, it will create a column with the column name from dgv1 and copy the values to an empty dgv2, which is correct.
 
However, when I press the button again, it will create a new column, but will replace all values in the first column. How do I set the column index so that each time I press the button, the values are copied to the correct column?
 
Thanks in advance.

 

private void button4_Click(object sender, EventArgs e)
      {
 
          List<int> selectedColumns = new List<int>();
          foreach (DataGridViewColumn col in  dataGridView1.Columns)
          {
              if (col.Index == columIndexFromMouseDown)
             {
                  dataGridView2.Columns.Add((DataGridViewColumn)col.Clone());
                  selectedColumns.Add(columIndexFromMouseDown);
                  listBox1.Items.Add(col.Index);
              }
 
          }
 
              int rowIndex = 0;
 
              foreach (DataGridViewRow row in dataGridView1.Rows)
              {
                  dataGridView2.Rows.Add();
                  for (int i = 0; i < selectedColumns.Count ; i++)
                  {
                      if (dataGridView2.Columns.Count ==1)
                      {
                          dataGridView2.Rows[rowIndex].Cells[i].Value = row.Cells[selectedColumns[i]].Value;
                      }
                      if (dataGridView2.Columns.Count > 1)
                      {
                          MessageBox.Show("asf");
                      }
                  }
 
               rowIndex++;
              }
 
          }
 
      }
