Refer here,
how to move rows up and down in gridview using asp.net?[^]

in case if you have up and down buttons in your grid rows

<asp:GridView ID="gv" runat="server" AutoGenerateColumns="False" OnRowCommand="gv_RowCommand">
     <Columns>
         <asp:TemplateField>............</asp:TemplateField>
     <asp:TemplateField>............</asp:TemplateField>
     <asp:TemplateField>............</asp:TemplateField>
         <asp:TemplateField>
             <ItemTemplate>
                 <asp:Button ID="btnDown" runat="server"

                     CausesValidation="false"

                     CommandName="Down" Text="↓" />
             </ItemTemplate>
         </asp:TemplateField>
     </Columns>
</asp:GridView>


protected void gvQuestion_RowCommand(Object sender, GridViewCommandEventArgs e)
{
    try
    {
       // Handle the Up command
       if (e.CommandName == "Up")
       {
           moveUp()
       }

       // Handle the Down command
       if (e.CommandName == "Down")
       {
           moveDown()
       }
}



private void moveUp()
    {
        if (dataGridView1.RowCount > 0)
        {
            if (dataGridView1.SelectedRows.Count > 0)
            {
                int rowCount = dataGridView1.Rows.Count;
                int index = dataGridView1.SelectedCells[0].OwningRow.Index;

                if (index == 0)
                {

                dataGridView1.Rows[index - 1].Selected = true;
            }
        }
    }

    private void moveDown()
    {
        if (dataGridView1.RowCount > 0)
        {

                // remove the next row and add it in front of the selected row.
