        this.categoriaTableAdapter.Fill(this.mioOilMixDataSet.Categoria);
        for (int item = 0; item < categoriaDataGridView.Rows.Count - 1; item++)




        {
            if (categoriaDataGridView.Rows[item].Cells[2].Value.ToString().Contains("A"))
            {

                CurrencyManager currencyManager1 = (CurrencyManager)BindingContext[categoriaDataGridView.DataSource];
                currencyManager1.SuspendBinding();
                categoriaDataGridView.Rows[item].Visible = true;
                currencyManager1.ResumeBinding();


            }
            else
            {
                CurrencyManager currencyManager1 = (CurrencyManager)BindingContext[categoriaDataGridView.DataSource];
                currencyManager1.SuspendBinding();
                categoriaDataGridView.Rows[item].Visible = false;
                currencyManager1.ResumeBinding();
            }



        }

    }

C#

What I have tried:

and this to navigate :

private void button1_Click(object sender, EventArgs e)
    {

        foreach (DataGridViewRow row in categoriaDataGridView.Rows)
        {
            if (row.Visible)
            {
                categoriaBindingSource.MoveNext();
                break;
            }

        }

Hi,

This happened because the record is in the grid, even though you do not see. The method MoveNext don't have control about the visibility the row, it move for the next record in the grid, visible or not.

To do what you want. Do like this:

C#

private void button1_Click(object sender, EventArgs e)
{
   //find the current position selected
   int indexrow = categoriaBindingSource.Position;

   //read the rows until find the first visible row
   for (int item = indexrow; item < categoriaDataGridView.Rows.Count - 1; item++)
   {
        //verify if the next rows is visible
        if (categoriaDataGridView.Rows[(item + 1)].Visible)
        {
            //move the selector for this position
            categoriaBindingSource.Position = (item + 1);
            break;
        }
   }
}
