Hope the below button click methods can help someone in implementing records navigation (backward and forward) in RadGridView.
private void btnPrev_Click(object sender, EventArgs e)
{
if (gridview1.CurrentRow.Index > 0)
{
gridview1.ChildRows[gridview1.CurrentRow.Index - 1].IsCurrent = true;
}
}
private void btnNext_Click(object sender, EventArgs e)
{
if (gridview1.CurrentRow.Index < gridview1.ChildRows.Count - 1)
{
gridview1.ChildRows[gridview1.CurrentRow.Index + 1].IsCurrent = true;
}
}
