              drditemB5.Items.Add(li);
              temp = dr[2].ToString();


          }

I am getting an error ' table 0 cannot found '
and if mentions explicitly the table name, error not come, the values doesn't populate in the dropdown list.

Verify that DataSet dsRes contains Table.

Is your query returning data?

Dataset doesn't contain table, i was check by if condition:

if (dsRes.Tables.Contains("accountitem"))
{
Response.Write("tABLE CONTAINS");
}

else
{
Response.Write("tABLE nOT FATCHED");
}

See if you want to use [0] with Dataset then you can check using :-
if(dsRes .Tables.count > 0)
{
foreach (DataRow dr in dsRes.Tables[0].Rows)
{
ListItem li = new ListItem();
if (temp != dr[2].ToString())
{
li = new ListItem(dr[2].ToString(), dr[0].ToString());
drditem1.Items.Add(li);
drditem2.Items.Add(li);
drditem3.Items.Add(li);
drditem4.Items.Add(li);
drditem5.Items.Add(li);
drditemB1.Items.Add(li);
drditemB2.Items.Add(li);
drditemB3.Items.Add(li);
drditemB4.Items.Add(li);
drditemB5.Items.Add(li);
}

li = new ListItem("-----" + dr[1].ToString(), dr[0].ToString());
drditem1.Items.Add(li);
drditem2.Items.Add(li);
drditem3.Items.Add(li);
drditem4.Items.Add(li);
drditem5.Items.Add(li);
drditemB1.Items.Add(li);
drditemB2.Items.Add(li);
drditemB3.Items.Add(li);
drditemB4.Items.Add(li);
drditemB5.Items.Add(li);
temp = dr[2].ToString();

}
}
