Hi Srikant S,
By default, the FillWeight property of the datagridviewcolumn is set to 100. This can only provide up to 655 columns.
If you want to impose a lower limit on the maximum number of columns, you can use a value of FillWeight greater than 1.
So you can set the FillWeight property to 1 in ColumnAdded event to get more columns.
Here is a simple code example.

private void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)  
{  
    e.Column.FillWeight = 1;  
}
