I wish this helpful for you Your loop is currently creating a new row only using the first 8 elements of your 'allLines' array.
You probably want to do something like this.
code :
for (int i = 0; i < allLines.Length; i += 8)
{
    dataGridView1.Rows.Add(allLines[i], allLines[i + 1], allLines[i + 2], 
    allLines[i + 3], allLines[i + 4], allLines[i + 5], allLines[i + 6], allLines[i + 7]);
}

like below fixes the issue More than likely one of your cells has a null value i.e.
dr.Cells["p1x"].Value == null

will help you How to loop each row that readed? in my code, the row won't bind to next row because of the same productID, so the datagridview won't move to new row, it still in the same row and overwrite the price (for some product, i have two price). How to loop it to show the same productID but it have different price. , You could loop through DataGridView using Rows property, like:
code :
foreach (DataGridViewRow row in datagridviews.Rows)
{
   currQty += row.Cells["qty"].Value;
   //More code here
}

I wish this helpful for you I am using DataGridView in vb.net. I would like to loop through a column and when a certain condition is met go to the next cell down and copy that into a cell in another column. So if I had 9, 1, 7, 66, 7, 9 in my first column, my second column would catch 66 and 9 the numbers that come after the specified 7. I have managed this in vba, but can't crack it in vb.net's datagrid. Any help appreciated. , Not sure if this is what you're looking for
Before
code :
Column1  | Column2
-------------------
   9     |
   1     |
   7     |
  66     |
   7     |
   9     |
Column1  | Column2
-------------------
   9     |
   1     |
   7     |
  66     |   66
   7     |
   9     |    9
  For i = 0 To DataGridView1.RowCount() - 1
      'Check condition
      If DataGridView1.Rows(i).Cells("Column1").Value = 7 Then
          DataGridView1.Rows(i + 1).Cells("Column2").Value = DataGridView1.Rows(i + 1).Cells("Column1").Value
      End If
  Next

I wish this helpful for you I know this is kind of a stupid question and i may sound a bit confused ('cause i really am).I'm programming a software for work but i'm new to c#. I have a Form with a TabControl. In each TabPage i have a DataGridView. , You can use foreach to loop over the DGVs:
code :
foreach (DataGridView dgv in new[] { dataGridView1, otherDGV })
{
    // code to happen to both DGVs goes here.
}

this one helps. I am creating a program that generates a bar code and then prints the shipping labels. , To iterate through every cell, you can use foreach loops
