Solution 1

Two possibilities here:
1) RowIndex is out of the range,
2) Cells is out of the range,

If it isn't the RowIndex, then it has to be the Cells - are there any?
Or...should that be dataGridView1 at all? The method name implies the control is called ExcelDGV...

Use the debugger to look at the parts of the line and see what you do have.
