Hello guys.I have a two buttons btn_Next and btn_Back and DataTable which is populated from database through a Adapter.
I want that after Database is Populated When i pressbtn_Next or btn_Back i can iterate over rows so if i press btn_Next row index 1 must be selected in response and if i press btn_Back rows index 0 and so on.

What I have tried:

I tried to count rows of datatable and then use it as length of datatable rows and for every click on btn_Next or btn_Back i m increasing or decreasing index accordingly.but i don't know where to use this index and how to use.

C#

private int _currRow =0; // declared in the class before any methods
private Datatable _theData // instaniated  somewhere in the class
private DataRow _dataRow;
private DataRow btn_Next_clicked(object sender, EventArgs e)
{
    
    if(_currRow<_theData.Rows.Count)
    {
      ++_currRow;
     
    }
   _dataRow =_theTable.Rows[_currRow];
  
    
}

I'll leave the prev button action for you
