And the question is?

((DataTable)GridView1.DataSource).Merge(dt2);
GridView1.DataSource = (DataTable)GridView1.DataSource;
GridView1.DataBind();
What's that? And I guess that's where you encounter a problem...

You didn't define the i you're using in the if line. Maybe that's outside of the code snippet you posted.

For me, it would be easier to read

C#

for(int rowIndex = 1; rowIndex < GridView1.Rows.Count; i++)
{
    if(GridView1.Rows[i - 1].Cells[4].Text == "Whatever")
    {
        DoSomething(GridView1.Rows[i - 1]);
    }
}

But why would you want to start your iteration at 1 instead of the usual 0 and then always use i - 1? Is there more code that acutally uses i to do something to two adjacent rows?

Otherwise you would be better off starting at 0 and using just i.
Or forget about iteration variables altogether and use the row variable from your question's code.
