There is no inbuilt function to get the index for given value but you can find the index through this function.

int cmbindex  = CmbIdxFindByValue("YourValue", cmbYourComboBox);

Function:

private int CmbIdxFindByValue(string text, ComboBox cmbCd)
    {
        int c = 0; ;
        DataTable dtx = (DataTable)cmbCd.DataSource;
        if (dtx != null)
        {
            foreach (DataRow dx in dtx.Rows)
            {
                if (dx[cmbCd.ValueMember.ToString()].ToString() == text)
                    return c;
                c++;
            }
            return -1;
        }else
            return -1;
    }
